本文实例为大家分享了Java界面编程实现界面跳转的具体代码，供大家参考，具体内容如下
在事件处理中创建对象
public void actionPerformed(ActionEvent e)
{
QQ1 qq1=new QQ1();//为跳转的界面
}
步骤：
在主函数中创建一个主窗口的对象
package 界面编程7;
public class QQmain {
public static void main(String[] args) {
// TODO Auto-generated method stub
QQ qq = new QQ();
}
}
编写QQ类，该类中调用QQ1类、QQ2类 表达不正确，反正就是调用被调用类的构造方法
package 界面编程7;
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;
import javax.swing.JOptionPane;
import javax.swing.JTextArea;
public class QQ extends JFrame implements ActionListener{
public QQ() {
this.setTitle("主界面");
this.setBounds(100, 100, 300, 400);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
FlowLayout layout = new FlowLayout();
this.setLayout(layout);
JButton jb1 = new JButton("弹出框");
JButton jb2 = new JButton("跳转1");
JButton jb3 = new JButton("跳转2");
this.add(jb1);
this.add(jb2);
this.add(jb3);
jb1.addActionListener(this);
jb1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
JOptionPane.showMessageDialog(null, "提示内容" ,"标题", 2);
}
});
jb2.addActionListener(this);
jb2.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
QQ1 qq1=new QQ1();//为跳转的界面
}
});
jb3.addActionListener(this);
jb3.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
QQ2 qq2=new QQ2();//为跳转的界面
}
});
}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
System.out.println("总处理");
}
}
QQ1类 该类中调用QQ2类
package 界面编程7;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
public class QQ1 extends JFrame implements ActionListener{
public QQ1() {
this.setTitle("界面1");
this.setBounds(200, 200, 300, 400);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
FlowLayout layout = new FlowLayout();
this.setLayout(layout);
JButton jb1 = new JButton("跳转");
this.add(jb1);
jb1.addActionListener(this);
}
@Override
public void actionPerformed(ActionEvent e) {
QQ2 qq3 = new QQ2();
}
}
QQ2类
package 界面编程7;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class QQ2 extends JFrame{
public QQ2() {
this.setTitle("界面2");
this.setBounds(200, 200, 300, 400);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
FlowLayout layout = new FlowLayout();
this.setLayout(layout);
JLabel jlb = new JLabel("界面2");
this.add(jlb);
}
}
