Java - AWT: Making objects point to other objects -

i begginer java programmer awt, , i'm wondering how make enemy() point player(). here code far:

player.java:

import java.awt.color; import java.awt.graphics; public class player extends gameobject {     public player(int x, int y, color color) {        super(x, y, color);     }      @override     public void tick() {         x += velx;         y += vely;     }      @override     public void render(graphics g) {         g.setcolor(color);         g.fillrect(x, y, 32, 32);     }    } 

enemy.java:

import java.awt.color; import java.awt.graphics;  public class enemy extends gameobject {     public enemy(int x, int y, color color) {         super(x, y, color);     }      @override     public void tick() {         x += velx;         y += vely;     }      @override     public void render(graphics g) {         g.setcolor(color);         g.fillrect(x, y, 32, 32);     }    } 

so how can begin moving enemy() towards player() game works?

you need reference gameobject somehow. you're missing in design. somewhere, in these 2 classes, or class, should keeping track of reference gameobject variable can set enemy player. there's no way arbitrarily make 1 class another.
