java - 如何在表单中显示 Netbeans 的输出？

Question

我知道输出可以保存到文件中，但我想知道 Netbeans 的输出结果是否可以显示在表单、文本框或其他内容中。

可能吗？

谢谢，

这是一个非常简化的示例，但是是的。可以将结果显示在表单中。

您需要做的是创建一个新表单（我使用了 JFrame 表单）。从那里，我在表单中添加了一个 JTextPane。

这应该是您在表单上需要的全部内容，只是为了显示结果。

之后，您只需将 textPane 的文本设置为您的结果并运行程序。

这就是我的代码的样子。

公共类 ResultsForm 扩展 javax.swing.JFrame {

/**
 * Creates new form ResultsForm
 */
public ResultsForm() {
    initComponents();
    this.TextArea.setText("No input");
    this.TextArea.setEditable(false);
}

//This is the constructor that takes in your results and places is
//in the form
public ResultsForm(String results){
    initComponents();
    this.TextArea.setText(results);
    this.TextArea.setEditable(false);
}

    jScrollPane2.setViewportView(TextArea);

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
