「java开发窗体窗口」java窗体程序
本篇文章给大家谈谈java开发窗体窗口,以及java窗体程序对应的知识点,希望对各位有所帮助,不要忘了收藏本站喔。

java如何设置透明窗体
1打开Java开发工具Eclipse软件,依次选择“文件”、“新建”、“项目”,在“新建项目”窗口中选择“Java项目”,然后点击“下一步”按钮。
2在出现的窗体中的“项目名称”后自定义输入项目名,然后点击“完成”按钮完成项目的创建。
3右击创建的项目,在右键列表中依次选择“新建”、“类”,在“新建类”窗体中输入自定义类名,勾选相应复选框,点击“完成”按钮完成类的创建。
4首先,做一些初始化窗体的工作,导入javax.swing.JFrame类,实现JFrame的继承,初始化构造方法头并在main方法内实例化此类以便做测试。
5下面,在构造方法中创建窗体,导入javax.swing.JButton类,在窗体内加入按钮,保持按钮默认的布局方式,最后设置窗体显示,运行程序查看初始效果。
6运行Java程序后,将出现初始化窗体界面,用户需关闭窗体做下一步代码的编写。
7添加按钮BTN的ActionListenr()单击事件,在出现的错误中点击错误处,然后自动导入ActionListener类,但是仍然出现错误,用户需再次点击错误处以添加必要的方法实现。
8当用户解决两次错误后,系统自动导入了所需包和加入了所需单击事件的必要方法。
9新建setOpacity()方法并在按钮的单击事件中调用此方法,然后在此类中作为属性成员加入JSlider滑块控件。
10在新建的setOpacity()方法中添加如下代码,设置dialog窗体的大小、位置、大小不可改变等属性,用户可自定义设置属性。
11创建JLabel,添加slider滑块的滑动事件,并在事件中加入方法slider(),当然此方法需要新建,待会再新建,让我们先把setOpacity()方法中的代码添加完成。
12继续在setOpacity()方法中添加代码,在窗体dialog中加入panel控件,再将lable和slider加入到panel中。
13在方法slider()中添加代码,获取slider的值以改变透明度值,设置鼠标移入滑块时的鼠标指针样式。
14运行Java程序,并点击按钮,然后出现调整透明度的窗体,用户就可以设置窗体透明度。
IntelliJ IDEA 如何开发java窗体程序?
主要步骤如下:
1、File——New Project
2、Next
3、输入Name,在Project files location中选择文件要存放的位置,Next
4、Next
5、选择要创建的项目或者直接点finish,创建简单的java项目
6、创建一个新类
7、如下:
8、输入代码:
9、Ctrl+Shift+F10,运行该类:
java怎么做窗体
如果是要进行AWT或者Swing编程需要将类打包成可运行的jar包或者通过工具将jar包打包成exe文件,然后点击就可以直接运行了。下面是一个简单的登录窗口例子:
效果图:
代码:
import java.awt.*;
import java.awt.event.*;
public class TestTextField implements ActionListener{
TextField name;
TextField password;
public static void main( String args[]) {
TestTextField ttf = new TestTextField();
ttf.createUI();
}
public void createUI(){
Frame f = new Frame("登录界面");
f.add(new Label("请输入您的用户信息:"),"North");
Panel p1 = new Panel();
p1.setLayout(new BorderLayout());
Panel p11 = new Panel();
p11.setLayout(new GridLayout(2,1));
p11.add(new Label("用户名:"));
p11.add(new Label("密 码:"));
Panel p12 = new Panel();
p12.setLayout(new GridLayout(2,1));
name = new TextField(10);
name.addActionListener(this);
password = new TextField(10);
password.setEchoChar('*');
password.addActionListener(this);
p12.add(name);
p12.add(password);
p1.add(p11,"West");
p1.add(p12,"Center");
Panel p2 = new Panel();
Button submit = new Button("提交");
Button reset = new Button("重置");
submit.addActionListener(this);
reset.addActionListener(this);
p2.add(submit);
p2.add(reset);
f.add(p1,"Center");
f.add(p2,"South");
f.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
f.setSize(200,130);
f.setLocation(300,200);
f.setVisible( true);
}
public void actionPerformed(ActionEvent e){
String s = e.getActionCommand();
if(s.equals("重置")){
this.clear();
}else if(s.equals("提交") || (e.getSource()==name) || (e.getSource()==password)){
this.submit();
}
}
public void clear(){
name.setText("");
password.setText("");
}
public void submit(){
String n = name.getText();
String psw = password.getText();
System.out.println("用户名:" + n + "\t密码:" + psw);
}
}

怎么用java写一个窗体程序?
下面介绍如何用简单的几句话在eclipse环境下出现一个窗口。
首先写一个frame类,继承Frame,是继承widows 然后把,出现窗口的语句封装成一个函数
public void lunchFrame(){
this.setLocation(0,0);
this.setSize(20,20);
setVisible(True); //一定要写这句话
}
最后只需要在主函数里面调用就可以
Java是一门面向对象编程语言,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杂的编程 。
Java具有简单性、面向对象、分布式、健壮性、安全性、平台独立与可移植性、多线程、动态性等特点 。Java可以编写桌面应用程序、Web应用程序、分布式系统和嵌入式系统应用程序等。
