Java 将信息从一个jframe传递到另一个jframe

这是转到新帧的按钮代码
JButton btnContinue = new JButton("Continue");

fram.setVisible(true);
frame.dispose();
我是swing新手,我不需要有人来完成我的程序。我只需要知道如何将它带到新框架上的新文本框中。框架与任何其他类类似,因此只需使用与在任何其他类之间传递数据相同的策略即可。例如,您可以简单地在第二个框架类中创建setter方法,并从第一个框架调用它们 注意:这是我在Netbeans中非常快速地组合起来的东西,因此生成了大量代码。而且,这是一个严格意义上的例子,我并不是说这一定是最好的方法 下面是一个简单的示例,说明了如何在两个
JFrame
对象之间传递数据:
这是Frame1中需要注意的代码:
private void sendToOtherFrameBtnActionPerformed(java.awt.event.ActionEvent evt) {
Frame2 otherFrame = new Frame2();
otherFrame.setTextFieldText(jTextField1.getText());
otherFrame.setTextAreaText(jTextArea1.getText());
otherFrame.setVisible(true);
}
以下是Frame1的完整代码:
public class Frame1 extends javax.swing.JFrame {
/**
* Creates new form Frame1
*/
public Frame1() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.

这样做相当容易。您所需要做的就是设置一个构造函数,在该构造函数中,您将需要的值传递给新帧
例如,我有一个LoginScreen.java和DoctorScreen.java。如果我的用户成功地输入了他的详细信息并登录,我将医生的ArrayList从一个JFrame转移到另一个JFrame,或者更准确地说,通过创建该类的新实例从一个java类转移到另一个java类
