java代码区图形化界面 java图形化界面写一个小程序

怎样用java编写图形界面的Application程序？

java编写图形界面需要用到swing等组件，可以在eclipse中安装windowbuilder来开发窗体，自动生成窗体代码租碰，然后自己再根据需要修改，如：

Java是一门面向对象御型消编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复镇知杂的编程。

java怎么实现图形化界面

java图形化界面还是有很多内容要学习的，可以余雹尘参考 如下实例：

public class Test extends JFrame{

MyPanel mp=null;

public static 竖禅void main(String[] args){

// TODO Auto-generated 肆运method stub

Test jf= new Test();

}

public Test(){

mp=new MyPanel();

this.add(mp);

//设置标题

this.setTitle("绘图");

//设置窗体大小

this.setSize(400, 300);

//设置窗体的位置

this.setLocation(100,100);

//限制窗体的大小

this.setResizable(false);

//关闭窗体时，同时退出java虚拟机

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//显示窗体

this.setVisible(true);

}

}

//定义一个MyPanel(我自己的面板，用于绘图和实现绘图区域)

class MyPanel extends JPanel

{

//覆盖JPanel的paint方法

//Graphics是绘图的重要类，可以把它理解成一只画笔

public void paint(Graphics g)

{

//1。调用父类函数完成初始化

super.paint(g);

// //画圆

// g.drawOval(100, 100, 20, 20);

// //画直线

// g.drawLine(50, 150,150, 200);

// //画矩形边框

// g.drawRect(150, 150, 30, 40);

//

// //设置颜色。默认为黑色

// g.setColor(Color.blue);

// //填充矩形

// g.fillRect(10, 10, 20, 30);

//画弧形

g.drawArc(200,10, 100,150, 120,-80);

//在面板上画图片

Image im=Toolkit.getDefaultToolkit().getImage(Panel.class.getResource("图片路径"));

//显示图片

g.drawImage(im, 10, 10,200,180,this);

//画字

g.setColor(Color.red);

g.setFont(new Font("华文彩云",Font.BOLD,20));

g.drawString("要写的字", 80,220);

}

}
