Instance methods

There is a class Robot for representing walking robots.

The robot lives on a 2-D plane. In this robot world, all distances are measured in steps. The robot can take some steps in any of the four directions: left, right, forward (up) and backward (down), but its coordinates are always limited: x >= 0, y >=0.

public class Robot {    
    int x, y;

    public void moveRight(int steps) {
        x += steps;
    }

    public void moveUp(int steps) {
        y += steps;
    }

    public void moveLeft(int steps) {
        x -= steps;
        if (x < 0) {
            x = 0;
        }
    }

    public void moveDown(int steps) {
        y -= steps;
        if (y < 0) {
            y = 0;
        }
    }
}

Where will the robot be after the following code is executed? Select a pair (x, y).

Robot ben = new Robot();

ben.moveRight(3);
ben.moveUp(2);
ben.moveLeft(4);
ben.moveUp(2);
ben.moveRight(1);

We suppose that the initial coordinates are (0, 0).
