program of infinite recursion

Answer 1

static void recInf (){System.out.println("hahaha"; recInf ();}

Answer 2

Is this what you mean? :

void recursiveMethod( ) {
while(true) {
recursiveMethod( );
}
}

Answer 3

More like,
void infiniteRecursion() {
infiniteRecursion();
}

we do not need while(true)

Answer 4

"infinite" is a very loose term here, as you will quickly get a stack overflow exception. It's often better performance wise to store results in your own stack object, and will avoid stack overflow exceptions.
