Yes, we can execute the java program with out the main
method by using the the static block. After executing the
static block the JVM will search for the main method so to
skip this we should call System.exit(int) method.

NOTE: System.exit method contains integer parameter so we
shoud pass the integer value.
class MainDemo
{
static
{
System.out.println("hello i am visible without
main");
System.exit(0);
}

}
