you can't do that in Java or in any other language. you have to create a separate method to do something and call that method within your switch statements. example:

class Example {
	public static void print() {
	 //... do some printing
	}

	public static void solve() {
	 //... do some solving
	}

	public static void main(String[] args) {
	
	   switch(ans) {
		   case 1:
			solve();
			break;
		   case 2:
			print();
			break;
		   default:
			// just nothing
	   }
	}
}

Is there any error / exception? Please post it.

		   case 2:
			print();
			break;
		   default:
			// just nothing
	   }
	}
}

you cant call solve(), break() because your main is static.

better make solve() , break as static too.

so you call it like Example.solve(), Example.break() etc.

^^ i wonder why TS does not have a problem with it. or does he even bother his problem from the start? hihi how rude.

yup you are correct. thanks for the heads-up!!!

will just declare solve() and print() static para ma call as it is sa main. i'm learning too in this thread too. haha

mas maau bro i post ang error ngari ma kahibawo ta why dli mo run imong script. but try the solution of silent-kill he has a point.

[skeptic_rob]

non-static method solve() cannot be referenced from a static context ang error sa solve(); ug print();

@TS
the best way to learn syntax (in any language) is to read up on it. there's just no substitute to reading.

so here straight from the horses mouth...

switch-case

static keyword
