如何使java写出程序可以使用图形界面 WindowBuilder Pro现在是google的开源项目https://developers.google.com/java-dev-tools/download-wbpro?hl=zh-CN在eclipse中建 立一个更新site,在线更新对应版本的插件。更新成功以后,新建的类,只要是继承了JFrame,JPanel在鼠标右键打开的里面就有windowBuilde这一项,打开以后,有代码视图及可视化视图如果不明白你留下联系方法吧。

java写一个图形程序,让数组输出在图形界面上 已把程序文件打包上传了,并附上运算结果图。import javax.swing.*;import java.awt.*;import java.util.*;import java.awt.event.*;class ShowDataInTheArrary extends JFrame{String data;JButton b1;JLabel l1;public ShowDataInTheArrary(String a){data=a;setTitle(\"Show Data in the array\");setLayout(new GridLayout(2,1));b1=new JButton(\"show\");l1=new JLabel();b1.addActionListener(new Monitor());add(l1);add(b1);pack();setDefaultCloseOperation(EXIT_ON_CLOSE);setVisible(true);}class Monitor implements ActionListener{public void actionPerformed(ActionEvent e){l1.setText(data);}}public static void main(String[]args){String arrayData=\";for(int i=0;i;i+)arrayData+args[i];ShowDataInTheArrary b=new ShowDataInTheArrary(arrayData);}}

C++,JAVA和C#,哪一个用于编写图形界面程序最强大?哪一个最易学? 毫无疑问 c++。JAVA和C#和大多用来做web应用的,c#跟asp关联,微软那套东西,是微软开发来跟sun干的,因为当初java在web应用上的强势让java迅猛发展,所以微软就搞了asp那套出来,跟sun的jsp那套干。c++是比较系统级的开发语言,c++是兼容c的,主流的3种操作系统Windows,Linux,Unix,内核都是用C语言和汇编写的,上层高级特性是用C++写的。《魔兽世界》等几乎所有的网络游戏,搜索引擎(Baidu.com),我们所用的多数桌面软件都是用C++写的(硬件也有很多用到C++的)。Java Virtual Machine 也是用c++来写的。所以,想做3d的话还是学c++吧!另外,c++是比JAVA和C#难的,甚至难很多!
