A premain method is launch in java from jdk 1.5 for instrumentation.
In a very simple world we can say that a premain method is used for get the size of the object resevered in heap area. It will return byte reserved by the object.
This method is similar to the sizeOf() function of c/c++.
In earlier version before 1.5 it was not possible to get the size of an object but after that you can get the bytes reserved by an object in heap with premain function.
No, Java only allows a method to be defined within a class, not within another method.

The getContentPane() method is used to get the main component in a Java Swing JFrame. It is usually a JPanel.
native is a key word used in java method. there is no variable as native in java
A void method is one that returns no value. The Java main() method is the first method to be called, therefore it doesn't need to return a value to another Java method, therefore it is declared as void. If something needs to be returned to the operating system, this is done differently, not by "returning a value" in the sense of Java.
There is no such thing as overlording in Java.
It is the method that gets called when a Java application is started.

In Java, a function is called a "method". In Java as well as other languages, a method is a function defined specifically for one class. In Java, this is the only way to define functions, therefore, all functions are methods.In Java, a function is called a "method".

A Java method is a sequence of statements. It is comparable to a function, subroutine, or procedure in other languages.

The Java superclass Object says that all Java objects have an equals method. Thus Comparator has an equals method.
