Is it important that java program should have main () method??is it possible that program may run without main()

Answer 1

/* No, it's not necessary with respect to Java7(http://stackoverflow.com/questions/15173474/can-we-execute-a-java-program-without-a-main-method) :
If there's code in a static block, it will be executed. But there's no point in doing that. */

public final class Test
{
static {
System.out.println("FOO");
}
}

/* Then if you try to run the class (either form command line with java Test or with an IDE), the result is:

FOO
java.lang.NoSuchMethodError: main */

// It's not supported here in the Code. P.
