THANK YOU

import java.awt.Color;

import java.awt.Graphics;

public class Apple {

private int xCoor, yCoor, width, height;

public Apple(int xCoor, int yCoor, int tileSize) {

this.xCoor = xCoor;

this.yCoor = yCoor;

width = tileSize;

height = tileSize;

}

public void tick() {

}

public void draw(Graphics g) {

g.setColor(Color.RED);

g.fillRect(xCoor * width , yCoor * height, width, height);

}

public int getxCoor() {

return xCoor;

}

public void setxCoor(int xCoor) {

this.xCoor = xCoor;

}

public int getyCoor() {

return yCoor;

}

public void setyCoor(int yCoor) {

this.yCoor = yCoor;

}

}

Please find commented code below::

Apple.java

package graphichal;

import java.awt.Color;
import java.awt.Graphics;

//creating class Apple
public class Apple {

   //added instance variable for x,y coordinates and width/height of apple
   private int xCoor, yCoor, width, height;

   //constructor for apple class
   public Apple(int xCoor, int yCoor, int tileSize) {

       //setting members by parameters
       this.xCoor = xCoor;

       this.yCoor = yCoor;

       width = tileSize;

       height = tileSize;

   }

   public void tick() {

   }

   //this function will be used to draw apple using parameter graphics
   public void draw(Graphics g) {

       //set color of apple to red
       g.setColor(Color.RED);

       //draw filled rectangle at position x,y with width and height
       g.fillRect(xCoor * width , yCoor * height, width, height);

   }

   //getter of x coordinate
   public int getxCoor() {

       return xCoor;

   }
   //setter of x coordinate
   public void setxCoor(int xCoor) {

       this.xCoor = xCoor;

   }
   //getter of y coordinate
   public int getyCoor() {

       return yCoor;

   }
   //setter of y coordinate
   public void setyCoor(int yCoor) {

       this.yCoor = yCoor;

   }

}
