column shows how you would reference those same keywords explicitly from a Java program. The third column shows an example of the context in which they might be used in a Java program. You may chose to statically import some of these classes into your code. I prefer to use the explicit p...
The abstract class and inheritance collectively ensures that most of the code are written using abstract and higher level classes, so that it can leverageInheritanceandPolymorphismto support future changes. This is actually one of the most useful design principle, also known as"Programming for interfa...
In Java SE 11, the Java Virtual Machine supports the arrangement of classes and interfaces into a new access control context, called a nest. Nests allow classes and interfaces that are logically part of the same code entity, but which are compiled to distinct class files, to access each othe...

If you stay up to date on news from the Java community, you may have heard that Oracle have changed their support model for Java. Some news is even suggesting that we now have to pay to use Java - th
Being in IT industry for almost 15 years, I have come across some most important Core Java Interview questions, which are frequently asked in most of the interv
To address this problem, we model software as a network, where the classes are the vertices in the network and the dependencies are the edges, and apply K-core decomposition to identify a core subset of vertices as potentially important classes. We study three open source Java projects over ...
However, It is not unusal to see the error “java.lang.OutOfMemoryError: PermGen space“if you are loading unusual number of classes. Gone are the days of OutOfMemory Errors due to PermGen space.With Java 8, there is NO PermGen. That’s right. So no more OutOfMemory Errors due to ...
