Quiz 1: A for loop statement.

What will happen if you try to compile and execute the main method?

public class MyLoop {

	int x = 5;
	int y = 7;

	void methodA(){
		for(int i = 0; i < 7; i ++ ) {
			System.out.print("-x" + x);
			if(y > x) {
				System.out.print("-y" + y);
				y -= 5;
				x -= 4;
				break;
			}else {
				System.out.print("-x" + x);
			}
		}
	}
	int methodB(int x, int y){
		if(this.y < 3) {
			return this.x + y;
		}else {
			return this.y + x;
		}
	}
	public static void main(String[] args){
		MyLoop myLoop = new MyLoop();
		myLoop.methodA();
		System.out.print("-x" + myLoop.methodB(6,3));
	}
}
