What is a method in Java?

There is no such thing as overlording in Java.

method invoking refers to the action in which we call a Java method from within another java method or class. Method invocation is analogous to a function call in procedural programming.

No, Java only allows a method to be defined within a class, not within another method.

1- What is the task of main method in a java program?

It is the method that gets called when a Java application is started.

Finalize method is used to remove non-java resources

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".

the main method in java tells the JVM from where to start execute the program

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

a method is a variable

The final and finally keywords have no impact on the return type of a method in Java.

The getContentPane() method is used to get the main component in a Java Swing JFrame. It is usually a JPanel.

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.

No. Java does not allow the declaration of methods within methods.

Java does not allow nesting of methods. You cannot declare a method inside another method

You declare a method final in Java when you do not want any subclasses of your class to be able to override the method. I have also heard that this allows the Java compiler to make more intelligent decisions. For example, it supposedly allows Java to decide when to make a method inline. (Note that this is all unconfirmed)

native is a key word used in java method. there is no variable as native in java

Yes you can very well do... the run method is nothing but a Java method and all properties applicable to Java methods are applicable to it also.

In Java, there are no functions. They call it method and you can define it within a class.

A method in java can declare only one return value and type at a time. For ex: a single method cannot have a code that returns a string in some cases and an integer in other cases. Java compiler does not let you do that. You can only have one return type for every method in java.

In Java, Java does support the concept of destructor, it's done via special method finalize.

The Java native method is a great way to gain and merge the power of C or C++ programming into Java. To use Java as a scientific and high performance language, when efficient native Java compilers are not fully implemented, use native method can boost the performance to at least the speed of C compiled code.

Nothing will happen. There is no restriction that every Java class must have a main method. The only program is that, this class cannot be executed as a standalone java program.

Java uses pass by value semantics by default.

dynamic method dispatch is a technique by which a call to a overridden method is solved at runtime rather than compile time..this is how java implements runtime polymorphism.
