how many methods are there in class runnable?

Tanmay Kadam,

What do you mean?

You can go to the JavaDoc and count class-specific methods.

You can recursively walk the class tree and get all inherited methods.

Neither method gives you the hidden, compiler-generated methods, though.

Likely the easiest method for you to count the methods is to use the reflection facilities. (see the java.lang.refle ct package)

Try starting with:

java.lang.Runnable.class.getMethods()

Cheers!

The only overloaded method is run(). Overloading that method is required to start a new Thread with Runnable. The other I know about is start(). When called it executes your run() method in the new Thread object.
