问题描述

我想写一个程序，可以绘制我分配给它的任何类型的形状，如

I want to write a program which can draw any type of shape that I assign to it like

1. Circle


2. Square


3. 矩形

我应该使用哪个库，以及如何使用我是用Java做的吗？

推荐答案

当然可以使用Swing来做到这一点。您可能需要查看Java的 Shape 库。

Sure you can do that using Swing. You may want to look into Java's Shape library for that.

或者你可以简单地覆盖Component的paint方法，如下所示。

Alternatively you can simply override the Component's paint method as shown below.

import javax.swing.*;
import java.awt.*;

public class ShapeTest extends JFrame{
     public ShapeTest(){
          setSize(400,400);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setLocationRelativeTo(null);
          setVisible(true);
     }

     public static void main(String a[]){
         new ShapeTest();
     }

     public void paint(Graphics g){
          g.drawOval(40, 40, 60, 60); //FOR CIRCLE
          g.drawRect(80, 30, 200, 200); // FOR SQUARE
          g.drawRect(200, 100, 100, 200); // FOR RECT
     }
}
