java图形界面源码

❶ 用java图形界面（GUI）写java代码

package com.test;

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class aaa extends JFrame implements ActionListener
{
JButton b1, b2 ; //定义两
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource() == b1 )
{
l1.setVisible(true);
}
if(e.getSource() == b2)
{
this.dispose();
}
}

❷ java图形界面编程

//这是哪个背景类
import java.awt.Image;
import java.awt.*;
import javax.swing.*;
public class ImageBack extends JPanel{

Image im = null;
public imageback(Image im){
this.im=im;
int width = Toolkit.getDefaultToolkit().getScreenSize().width;
int height = Toolkit.getDefaultToolkit().getScreenSize().height;
this.setSize(width,height);
this.setVisible(true);
}
public static void main(String args[]){

}
public void paintComponent(Graphics g){
//清屏
super.paintComponent(g);
g.drawImage(im, 0, 0, this.getWidth(),this.getHeight(),this);
}
}
import javax.swing.*;

import java.io.File;
import java.io.IOException;
import java.net.*;

/**
* 学生管理系统主界面
*/
public class StuMain extends JFrame{
//背景图片
Image image=null;
public StuMain() {
try {
image = ImageIO.read(new File("images/start.jpg"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//把你要的背景图片放到背景面板里
imageback im = new imageback(image);
//把有背景的图片的JPanel放到JFrame里面
this.add(im);
//添加框架的关闭事件处理
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.pack();
//设置框架的大小
//设置标题
this.setTitle("学生管理系统");
this.setVisible(true);
}
public static void main(String args[]){
new StuMain();
}
}

❸ 求一个Java程序代码要运用图形界面

package gussNumber;
import java.awt.*;
import java.awt.event.*;

public class GussNumber extends Frame{
private static GussNumber mainFrame = new GussNumber();
private static Button yes = new Button("确定输入");
private static Button reTry = new Button("重新测试");
private static Label lb = new Label("请输入你猜测的数字(0~100):");
private static Label ts = new Label("欢迎使用......");
private static Double r_num = new Double(Math.random()*100);
private static Integer num = new Integer(r_num.intValue());
private static int t_num;
private static TextField tf = new TextField("",5);
private static String ct_img = "welcome.jpg";

public void paint(Graphics g){
Image img = getToolkit().getImage(ct_img);
g.drawImage(img,100,30,this);
}
public GussNumber(){
addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
dispose();
System.exit(0);
}
});
}
public static void main (String[] args) {

yes.addActionListener(new ButtonListener());
reTry.addActionListener(new ButtonListener());
System.out.println("Starting GussNumber...");
mainFrame.setBackground(Color.WHITE);
mainFrame.setSize(400,200);
mainFrame.setLayout(null);
mainFrame.setLocationRelativeTo(null);
mainFrame.setTitle("猜数字");
mainFrame.add(lb);
lb.setBounds(70,150,200,20);
mainFrame.add(tf);
tf.setBounds(270,150,50,20);
mainFrame.add(yes);
yes.setBounds(240,170,60,25);
mainFrame.add(ts);
ts.setBounds(70,130,200,20);
mainFrame.add(reTry);
reTry.setBounds(100,170,60,25);
mainFrame.setResizable(false);
mainFrame.setVisible(true);
}
static class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent event) {
if(event.getSource()==yes){
try{
t_num = Integer.parseInt(tf.getText());
}catch(NumberFormatException e){
Graphics g = mainFrame.getGraphics();
Image img = mainFrame.getToolkit().getImage("welcome.jpg");
ct_img = "welcome.jpg";
ts.setText("请输入正常的数字！");
g.drawImage(img,100,30,mainFrame);
}
if(t_num == num){
ct_img = "right.jpg";
ts.setText("答对啦！ 恭喜你~");
Image img = mainFrame.getToolkit().getImage("right.jpg");
Graphics g = mainFrame.getGraphics();
g.drawImage(img,100,30,mainFrame);
}
if(t_num > num){
ct_img = "tooBig.jpg";
ts.setText("大了点哦! 继续努力~");
Image img = mainFrame.getToolkit().getImage("tooBig.jpg");
Graphics g = mainFrame.getGraphics();
g.drawImage(img,100,30,mainFrame);
}
if(t_num < num){
ct_img = "tooSmall.jpg";
ts.setText("试试换个大点的数字~");
Image img = mainFrame.getToolkit().getImage("tooSmall.jpg");
Graphics g = mainFrame.getGraphics();
g.drawImage(img,100,30,mainFrame);
}
}
if(event.getSource()==reTry){
Image img = mainFrame.getToolkit().getImage("welcome.jpg");
Graphics g = mainFrame.getGraphics();
g.drawImage(img,100,30,mainFrame);
r_num = new Double(Math.random()*100);
num = new Integer(r_num.intValue());
tf.setText("");
}
}
}
}

记得将图片换成自己的图片；
并且布局修改得美观点。。。。

❹ 求一个简单的java代码：（图形界面）

直接写main函数里了
public static void main(String[] args) {

JFrame ck = new JFrame("title");
JPanel mb = new JPanel();
mb.setLayout(null);
String str = "test"; //自己定义要显示什么
JTextArea ta = new JTextArea(str);
ta.setBounds(0, 0, 100, 30); //自己定义文本区在窗口中的位置和大小
mb.add(ta);
ck.add(mb);
ck.setVisible(true);
ck.setBounds(200, 200, 500, 500); //自己定义窗口位置和大小

}

❺ java图形界面设计实验，求源代码，谢谢大佬！

代码：

import java.awt.*;

import javax.swing.*;

public class W extends JFrame

{

public static void main(String[] args)

{

new W();

}

W()

{

JPanel p=new JPanel();

JButton b=new JButton("ok");

b.addActionListener(e->

{

b.setForeground(Color.BLUE);

b.setText("鼠标点击！");

//setTitle("鼠标点击！");

});

p.add(b);

add(p,BorderLayout.NORTH);

setTitle("事件测试窗口");

setSize(200,150);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setVisible(true);

}

}

运行结果截图：

❻ java图形界面代码解惑

一般来说.比较常使用的是JTextArea文本框的无参数构造器进行构造

然后可以使用setText("文字")来设置文本,或者getText()方法来获得文本

JTextAreajta=newJTextArea();
jta.setText("你好啊");
Stringtxt=jta.getText();

具体例子

importjava.awt.*;
importjava.awt.event.*;
importjava.io.*;
importjavax.swing.*;

{
	JTextAreajta;
	JTextFieldjtf;
	JButtonjb;
	publicReadBook(){
		jta=newJTextArea();
		jtf=newJTextField(30);
		jtf.setText("文件路径如c:\ab.txt");
		jb=newJButton("显示文字");
		JPaneljp=newJPanel();
		jp.add(jtf);
		jp.add(jb);
		add(jta);
		add(jp,BorderLayout.SOUTH);
		setBounds(500,100,500,380);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setVisible(true);
		
		jb.addActionListener(newActionListener(){
			
			@Override
			publicvoidactionPerformed(ActionEvente){
				Stringpath=jtf.getText();
				Filef=newFile(path);
				if(f.exists()&&!f.isDirectory()){//存在该文件且不是文件夹
					try{
						StringBuildersb=newStringBuilder();
						BufferedReaderbr=newBufferedReader(newFileReader(f));
						Stringtemp;
						while((temp=br.readLine())!=null){
							sb.append(temp+"
");
						}
						br.close();
						jta.setText(sb.toString());//setText方法可以给jta添加文字

					}catch(Exceptione1){
						e1.printStackTrace();
					}
					
				}else{
					jtf.setText("路径错误.重新填写");
				}
			}
		});
		
	}
	publicstaticvoidmain(String[]args){
		newReadBook();
	}
}

效果

❽ java图形界面谁能做出这样的界面只需要一个界面求源代码

用javaFX更简单。拖一拖就可以了，不过需要JavaFX Scene Builder 2.0
用NetBeans IDE创建swing项目也是拖一拖就可以了
