calling of main()

[pinto rajput]

sir,
i want to know that can a main method of a class be invoked in another class,if yes how .explain me with an example.

You can do it. I don't know why you need someone to provide an example.
Why can't you write 2 classes and try calling the main method of one class from the main method of another class?

The only thing special about main is that it's the one that gets run if you say 'java SomeClass' on the command line. Of course it only works if the signature is just perfect (static, with string array for parm, you know). I wouldn't call it, though. I'd do something like this if I had the need:

public class Test {
    public static void main(String[] args) throws Exception {
        Test2.someNonMainMethod(args);
    }
}
 
class Test2 {
    public static void someNonMainMethod(String[] args) throws Exception{
        byte[] globOfStuff = "XyZ123+test".getBytes();
        BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream("aFile.dat"));
        out.write(globOfStuff);
        out.flush();
        out.close();
        BufferedInputStream in = new BufferedInputStream(new FileInputStream("aFile.dat"));
        byte[] glob2 = new byte[in.available()];
        in.read(glob2);
        System.out.println(new String(glob2));
    }
    public static void main(String[] args) throws Exception {
        someNonMainMethod(args);
    }
}
