I love to see a change in political scenario of India, Gandhigiri I like but his political stance I dont really. I used to love BJP but cant associate with it any longer. I used to love naxalism, wanted to be one in fact but something really changed, they sound good in movies and paper, in reality I now doubt the truth in their fight.
JP and his ideology I love, coming to practicality I doubt some implementations. I love CBN, consider him a great administrator but there is something I cant really point which bothers me :. I hate corruption but sometimes have to go along to just survive.
I love movies and anything related to showbiz but get pissed off with a few overrated people. I love people in general but in specific I hate parasites.
I am proud of my place of birth, caste, religion, country but I hate those who differentiate based on any of these. I love the concept of a global citizen. Love nature, am concerned about the fact that we are so busy accumulating wealth for our future generations forgetting that is basic needs like air and water that will sustain them and not the paper currency.
A bundle of contradictions basically Basically, I never get into anyone's way. I now go by one simple funda in life. Hello Thanks for the material. You are commenting using your WordPress.

Dec 20, Jan 22, Jul 5, Initial commit. Nov 17, Update default-static-interface-methods. Feb 23, This Java 8 tutorial list down important Java 8 features with examples which were introduced in this release.
All features have links to detailed tutorials such as lambda expressions, Java streams, functional interfaces and date time API changes.
Java SE 8 was released in early In java 8, most talked about feature was lambda expressions. Lambda expressions are not unknown to many of us who have worked on other popular programming languages like Scala. In Java programming language, a Lambda expression or function is just an anonymous functioni.
Please note that based on type of x and y, method may be used in multiple places. Parameters can match to int, or Integer or simply String also. Based on context, it will either add two integers or concat two strings. As name suggest, they permit exactly one abstract method inside them. Java 8 introduces an annotation i. FunctionalInterface which can be used for compiler level errors when the interface you have annotated violates the contracts of Functional Interface.
Please note that a functional interface is valid even if the FunctionalInterface annotation would be omitted. It is only for informing the compiler to enforce single abstract method inside interface. Another important point to remember is that if an interface declares an abstract method overriding one of the public methods of java. Object or elsewhere. Java 8 allows you to add non-abstract methods in interfaces.
These methods must be declared default methods. Default methods were introduces in java 8 to enable the functionality of lambda expression. Default methods enable you to add new functionality to the interfaces of your libraries and ensure binary compatibility with code written for older versions of those interfaces. Moveable interface defines a method move and provided a default implementation as well. It can directly call instance.
Another major change introduced Java 8 Streams APIwhich provides a mechanism for processing a set of data in various ways that can include filtering, transformation, or any other way that may be useful to an application. Streams API in Java 8 supports a different type of iteration where you simply define the set of items to be processed, the operation s to be performed on each item, and where the output of those operations is to be stored.
An example of stream API. In this example, items is collection of String values and you want to remove the entries that begin with some prefix text. Here items.

Date class has even become obsolete. If you want to use the date functionality with zone information, then Lambda provide you extra 3 classes similar to above one i. This is done via using another class i. For representing the specific timestamp ant any moment, the class needs to be used is Instant. The Instant class represents an instant in time to an accuracy of nanoseconds.
Operations on an Instant include comparison to another Instant and adding or subtracting a duration. Duration class is a whole new concept brought first time in java language.Posted by SmlCodes. He teaches the core java for the beginners and also will. Which of the following are valid java identifiers? Skip to main content. The main concepts covered in this part II: Create your own flipbook. Coding standards for variables: Reserved words for data types: Floating point literal is by default double type but we can specify explicitly as float type by suffixing with f or F.
It is always no argument method. Local variables Instance variables: Method name should be prefixed with add.
A java bean is a simple java class with private properties and public getter and setter methods. Nataraj from Ameerpeta Core Java notes by Mr. Click here to sign up. It seems to be overriding concept is applicable for static methods but it is not overriding it is method hiding.
To hold the no. In java we have only new keyword but not delete because destruction of useless objects is durgasoftt responsibility of Garbage Collection. Of arguments such type of methods are called var-arg methods. Any sequence of characters with in double quotes is treated as String literal.
Coding standards for classes: We can resolve this problem by using collections. Return type should not be void. Day after day he was bringing less and lesstrees. Total how many objects created? If we are taking array size with -ve int value then we will get runtime exception saying NegativeArraySizeException. Of characters present in a big file int may not enough hence the return type of length method is long. Ithought that like me, there may be millions of my brothers and sisters across the nation facing same kindof problem.
A B Types of Variables Division 1: Fixed in size that is once materiao created an array there is no chance of increasing or decreasing the size based on xurgasoft requirement that is to use arrays concept compulsory we should know the size in advance which may not possible always.
Now I am not alone in chasing this challenge. Multi dimensional array creation: It returns the no of characters present in materixl String. If we are just busy in applying for jobs, when we will sharpen our skills to chase the job selection process?
For every rurgasoft the JVM will create a Runtime stack all method calls performed by that Thread and corresponding local variables will be stored in that stack. The local variables will be created as part of the block execution in which it is declared and destroyed once that block execution completes.
Native method invocations will be stored in native method stacks. It should be public. The only allowed characters in java identifiers are: The main objective of command line arguments are we can customize the behavior of the main method.
Java is not considered as pure object oriented programming language because several oops features like multiple inheritance, operator overloading are not supported by java moreover we dyrgasoft depending on primitive data types which are non objects. I have been working in Java and JEE technologies.Java 1.8 New Features : Streams by durga sir
Whenever we are performing array assignments the types and dimensions must be matched but sizes are not important. In java we are allowed to use any worldwide alphabets character and java is Unicode based and no. The main advantage of this approach is to mxterial memory utilization.To browse Academia.

Large amounts of money and time are spent in re-designing the product, which causes heavy delays.
In this article, the author will give some simple advice and examples of test methods useful for avoiding undesired emission. Current lead-free soldering temperatures can damage temperature sensitive components. An easy way to solve this problem is to use a soldering alloy with a lower melting point that allows for lower soldering temperatures. Currently however these alloys have limitations in shock and vibration resistance.I thought they were wonderful and that contributed to our having an amazing time and wanting to return to Iceland.
My wife and I wanted to sample two contrasting lifestyles of Scandinavia - the more rustic one of the Arctic circle and the urban quality of the cities.
As nothing seemed to fully satisfy my needs I decided to contact Nordic Visitor and asked for advice. It turned out to be a great decision - their impressively broad offer was explained to me in exhaustive detail by a Nordic Visitor Travel Consultant who was also able to make suggestions when I requested for it.
My final choice was a combination of two existing tours with certain modifications to suit all my needs. The care of all the details (including upgrades of the transport classes I decided to request for later) was taken by the Nordic Visitor Travel Consultant who did a fantastic job - everything was done promptly and worked impeccably throughout the entire tour.
Nordic Visitor is highly recommended if you want to have a stress-free experience in booking your holiday and afterwards focusing on nothing more but on the enjoyment it brings.
We used Nordic Visitor to book our Iceland new year trip fairly last minute. Can't fault them - we had a fantastic experience and the whole process was so straightforward and felt effortless.
Before travelling we were in regular contact with our agent (Hafdis) who was quick to respond on working days and answered all our questions. We were free to book extra activities as and when we found them (which we did a few times. They were easy to contact whilst in Iceland as they gave us a local mobile phone with credit. We got upgraded rooms in half the (fantastic) hotels we stayed in and our car was upgraded too. Thanks for your help - our trip was great. I am a lifelong independent and pragmatic traveller who is used to arranging and organising all aspects of my trips including rearranging etc.
This was my first time booking an organised package and have been more than pleased with your outstanding service and very happy that I chose you.
We were extremely satisfied with the services provided. Nordic visitor supplied us with everything and more needed to make our vacation in Iceland a dream come true. We have already recommended them to our family planning a trip next year.
I used Nordic Visitor to book our honeymoon in Iceland and it was wonderful. We wished our time there would never end. Thank you Nordic Visitor. My husband and I chose to do the 10 day self guided Romance Around Iceland tour for our honeymoon. It couldn't have been more perfect. Nordic Visitor planned every detail for us, including having gourmet chocolates and champagne waiting for us in our room, booking all of our accommodations, excursions, rental cars and taxi rides, and provided us with ample information about navigating through Iceland.
They even provided us with a cell phone and called to check in while we were travelling through an area close by to an active volcano. I think it is safe to say I have fallen head over heels in love with Iceland. It has been 6 months since we came home and I still think about it daily.
I would recommend Nordic Visitor to anyone looking for a truly customized and memorable trip. The tour we booked was a perfect introduction to Scandavia and Norway in particular.
The highlights noted in the itinerary were well thought out and offered fantastic sight seeing. All our questions before departure were answered fully and promptly by Bjarni and the booking processs was easy. As we received the itinerary well before departure we were able to make enquiries about parking at each location directly with the hotel and all of them responded with excellent information. The car we were given for the tour was perfect and the driving experience in Norway was a real pleasure.
A trip of a lifetime for us The communication between Nordic Visitor and us was great. Irja was very good at responding to any and all e-mails sent. The people who worked at the rental car agency and the hotels were very nice and helpful. The Swedish people were amazing in how they switched to English as soon as they figured out that we spoke only English.
We know for sure that we got upgraded in two of the hotels that we stayed in (Karlstad and Kalmar) and two of the hotels (Vaxjo and Kalmar) provided not only the complimentary breakfast, but also a delicious complimentary dinner.
