If the resource name begins with '/', then the path is absolute - taken from the root of the class path. Otherwise, the resource is relative to the package folder of the Class you are invoking the method upon.

Migrating provides the ability to target to a specific Java Runtime Environment version or a specific version range. Java Web Start technology supports multiple, simultaneous versions of the Java Standard Edition platform. Specific applications can request specific Java versions without conflicting with the different needs of other applications.

Threads are great if some part of the processing is waiting on something external the thread that's waiting can continue to wait, while a thread that isn't waiting forges on ahead. For processing-intensive tasks, more threads than processors actually creates overhead.
NullPointerExceptions are exceptions that occur when you try to use a reference that points to no location in memory (null) as though it were referencing an object. Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.

I had suffered this problem too. Whenever we delete a tomcat server and run our project in new one without build classpaths and clean and build that project, we got this type of exceptions.

So, Build your projects classpath. Goto property of your Project then Select =>Java Build Path => Order and Export. Select All classpaths.

The double colon operator :: is used for method references in Java. This concept was introduced as part of Java 8. Using a method as a reference, for a matching functional interface is referred to as the method reference in Java.
Garbage Collection is process of reclaiming the runtime unused memory automatically. In other words, it is a way to destroy the unused objects.It makes java memory efficient because garbage collector removes the unreferenced objects from heap memory.

Java has "static nested classes", but they're not at all the same as C#'s static classes, if that's where you were coming from. A static nested class is just one which doesn't implicitly have a reference to an instance of the outer class. Static nested classes can have instance methods and static methods.

Java is not the best language to do anything BUT with Java you could do everything and anything. Great yes. Android framework was developed in C++ but Android application's​ are develop in Java. Your question itself is ambiguous. Hope you got it now. All the best and cheers.

You created the array but didn't put anything in it, so you have an array that contains 5 elements, all of which are null. You could add

boll[0] = new ResultList();

Memory leak in Java is a situation where some objects are not used by the application any more, but GC fails to recognize them as unused. As a result, these objects remain in memory indefinitely, reducing the amount of memory available to the application.

There are a number of sources in various places. Some of the ones that come to mind are:

1. The Jenkins open source project, itself. For example: Use Jenkins - Jenkins - Jenkins Wiki
2. IRC specifics: IRC Channel - Jenkins - Jenkins Wiki
3. The Jenkins CI blog: Home - Jenkins - Jenkins Wiki
Sometimes you do start the debug mode but the debugger doesn't actually get attached/gets detached. I've also had this issue a few times when my laptop was reacting really slowly. A reboot always solved it for me

Take source code and add it to your eclipse workspace.

Click on your project (Right Click) -> Debug As -> Debug Configuration -> Source Tab
