创建Bug类，该类将移回原始位置

Question

I'm very new to Java and I'm confused on how to create a method that goes back to original position, going through each step and turn.

This is an assignment for school and essentially, I have to create a Bug class, which moves 1 unit of distance on a horizontal line, turns, reverses, and moves back to original position.

Here's the code I have so far:

public class Bug
{
    private int position;
    private String direction;

    public void initialPosition(int position ) {
        position=0;
    }

    public void initialDirection(String direction) {
        direction="right";
    }

    public void setPosition (int position) {
        this.position = position;
    }

    public int getPosition() {
        return position;
    }

    public void setDirection (String direction) {
        this.direction = direction;
    }

    public String getDirection() {
        return direction;
    }

    public void move() {
        position+=1;
    }   

    public void reverseDirection() {
        if (direction=="right") {
            direction="left";
        }
        else {
            direction="right";
        }
    }

    public String toString() {
        return "Position: " + position + " & Direction: " + direction;
    }
}

Any tips on code will be super appreciated as well. Thanks!

Answer 1

In your move() function, get the current direction and then use an if statement so that

if (direction.equals("right")) {
    position+=1;
} 
else {
    position-=1;
}
