JAVA: can you help me to understand how to get the xPos and yPos

public void move (int xPos, int yPos) { while (this.body.getWidth() > 0) { this.head.setXPos(this.head.getXPos() + xPos or yPos); this.body.setXPos(this.body.getXPos() + xPos or yPos); this.leg.setXPos(this.leg.getXPos() + xPos or yPos); this.delay(20); } return; }

I need basically to move the body of the marionette in the x and y-axis and also animate it
