「Java简单白板」java简单程序例子

博主:adminadmin 2023-01-15 09:15:09 318

今天给各位分享Java简单白板的知识,其中也会对java简单程序例子进行解释,如果能碰巧解决你现在面临的问题,别忘了关注本站,现在开始吧!

本文目录一览:

刚学习java图形界面的开发,刚建立个JFrame窗口就出现了如下代码,请高手在每个语句后给个注释就可以:

import java.awt.BorderLayout;

public class Base extends JFrame { //承继GUI说明当前类是个GUI程序类

private JPanel contentPane; //定义一个白板

/**

* Launch the application.

*/

public static void main(String[] args) {

// 使用事件线程来启动界面初始化,不会形成卡机

EventQueue.invokeLater(new Runnable() {

public void run() {

try {

Base frame = new Base(); //创建面板容器

frame.setVisible(true); //让面板容器显示出来

} catch (Exception e) {

e.printStackTrace();

}

}

});

}

/**

* Create the frame.

*/

public Base() {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//定义当容器被关闭时将结束GUI的线程

setBounds(100, 100, 450, 300);//定义了容器的大小和屏幕出现的位置

contentPane = new JPanel();//初始化一个白板

contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));//白板的边角使用空边角

contentPane.setLayout(new BorderLayout(0, 0));//白板里的元素将使用边界式的布局

setContentPane(contentPane);//把白板放到容器里

}

}

JAVA 我用其他的布局方式都会有显示,但用BorderLayout就只出来一块白板是怎么回事啊,代码如下

把setVisible(true);这句移到public Calculator()构造函数的末尾,按钮就显示出来了,

另外for(int i=0;i12;i++)应该改成for(int i=0;i16;i++)因为你有16个按钮

完整的Java程序如下(改动的地方见注释)

import java.awt.GridLayout;

import javax.swing.JButton;

import javax.swing.JFrame;

import javax.swing.JPanel;

import javax.swing.JTextField;

import java.awt.BorderLayout;

class Calculator extends JFrame{

 private JPanel pan= new JPanel();

 private JButton button;

 private JTextField text;

 String number[]={"7","8","9","/","4","5","6","*","1","2","3","-","0",".","=","+"};

 public Calculator() {

  super("小神童计算器");

  setSize(600,600);

  setLayout(new BorderLayout(5,5));

  text=new JTextField("请输入数字",20);

  pan.setLayout(new GridLayout(4,4));

  for(int i=0;i16;i++){ //这里i12;改成i16;

   button=new JButton(number[i]);

   pan.add(button);

  }

  pan.setVisible(true);

  //add(text,BorderLayout.NORTH);

  add(pan,BorderLayout.CENTER);

  setDefaultCloseOperation(EXIT_ON_CLOSE);

  setVisible(true);//这里把setVisible(true);移到这里

 }

}

public class test {

 public static void main(String [] args){

  Calculator cal=new Calculator();

 }

}

运行结果

求助高手用java编写一个用于网络教学的电子白板

我这里有,不过怎么能在这里留下。别人是不会把代码留到这里的。我还可以给你介绍个人他哪里也有QQ 42396542 祝你好运了。呵呵。。

JAVA实现简单的画图板

楼主写一个html,很容易把下面代码嵌入到applet,可以google一下实现,

还有copy自己不知道算不算复制。。。-_-!

--------------------------------------------------------------------

楼主给你一个我的,直接保存成pb.java编译运行,就是你要的画图功能 ,可以参考一下

云南java培训学校告诉你web开发常见的开发工具介绍?

对于程序员来说,好的开发工具能够大大提高编程开发的工作效率,节约更多的时间来从事其他方面的工作。今天,昆明北大青鸟就一起来聊聊关于web前端开发过程中的常见开发工具都有哪些。

SublimeText

SublimeText是一个轻量、简洁、高效、跨平台的编辑器,方便的配色以及兼容vim快捷键等各种优点博得了很多前端开发人员的喜爱!SublimeText2这款程序员必备代码编辑器,几乎每位程序员提到SublimeText2都是赞不绝口!它体积小巧,无需安装,绿色便携;它可跨平台支持Windows/Mac/Linux;支持32与64位操作系统,它在支持语法高亮、代码补全、代码片段(Snippet)、代码折叠、行号显示、自定义皮肤、配色方案等所有其它代码编辑器所拥有的功能的同时,又保证了其飞快的速度!

picpick

PicPick是一款免费截图软件,它可以抓取全屏幕或是局部的画面,而且操作也很简单,还具备了一般常用到的基本图像编辑、屏幕尺、角度、测距、及屏幕演示白板等功能。在前端学习开发中非常有。

git
