在 Java AWT 中显示图形的最简单方法是什么？

Question

I want to use a parent class, preferably Component (being the highest up AWT gui class I'm aware of). I'm not a newbie to programming but I am self taught and am having problems getting example code for my question. Here's my code:

import java.awt.Frame;
public class DrawSquare extends Frame{
    public DrawSquare(){
        setBounds(0,0,100,100);
        setVisible(true);
    }
    public static void main(String[]args){
        new DrawSquare();
    }
}

Basically I want to do the same thing with a parent class to 'possibly' have quicker and more efficient code. I'm assuming that Frame has more in built options such as a border while Window (a parent class) does not, but I have only been able to make this simple code with Frame.

I want to use AWT, not swing btw.

Answer 1

According to my tests:

class C extends Component {
  public C() { setSize(200, 200); setVisible(true); }
  public void paint(Graphics g) {
    g.drawRect(0, 0, 100, 100);
  }
}

will not be displayed because presumably it needs something to be added to.

class C extends Container {
  public C() { setSize(200, 200); setVisible(true); }
  public void paint(Graphics g) {
    g.drawRect(0, 0, 100, 100);
  }
}

will not be displayed because it is a container so it needs other things to be added to it.

class C2 extends Window {
  public C2() { super(new Frame()); setLocation(100, 100); setSize(200, 200); setVisible(true);  }
  public void paint(Graphics g) {
    g.drawRect(0, 0, 100, 100);
  }
}

can be displayed but has nothing to grab around and it even doesn't show on the task bar so its a useless thing unless you add it somewhere.

So

class C extends Frame {
  public C() { setSize(200, 200); setVisible(true);  }
  public void paint(Graphics g) {
    g.drawRect(0, 0, 100, 100);
  }
}

is your solution as the first that is both a Component and a Container.
