任何人都可以告诉我如何在获取值后更改 a1、a2、a3、a4、a5 的字体，jTextFields这样如果我在我的显示上显示它JOptionPane，每个变量的赋值都有颜色

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    String a1 = jTextField1.getText();
    String a2 = jTextField2.getText();
    String a3 = jTextField3.getText();
    String a4 = jTextField4.getText();
    String a5 = jTextField5.getText();

    String m1 = "You will never forget " + a1 + "\n\n";
    String m2 = "You can consider " + a2 + " as your true friend \n\n";
    String m3 = "You really Love " + a3 + "\n\n";
    String m4 = a4 + " is your twin soul \n\n" ; 
    String m5 = "you will remember " + a5 + " for the rest of your life (due to past –good or bad- experiences, lessons etc) \n\n";
    String m6 = m1 + m2 + m3 + m4 + m5;
    JOptionPane.showMessageDialog(null,m6);
}

请参阅如何在 Swing 组件中使用 HTML。例子：

String m1 = "<html>You will never forget <b>" + a1 + "</b></html>";

现在a1将以粗体显示。

你应该创建Label，设置Font，然后用它来创建messageDialog。尝试这样的事情：

String a1 = jTextField1.getText();
String a2 = jTextField2.getText();
String a3 = jTextField3.getText();
String a4 = jTextField4.getText();
String a5 = jTextField5.getText();

String m1 = "You will never forget " + a1 + "\n\n";
String m2 = "You can consider " + a2 + " as your true friend \n\n";
String m3 = "You really Love " + a3 + "\n\n";
String m4 = a4 + " is your twin soul \n\n" ; 
String m5 = "you will remember " + a5 + " for the rest of your life (due to past –good or bad- experiences, lessons etc) \n\n";
String m6 = m1 + m2 + m3 + m4 + m5;

JLabel label = new JLabel(m6);
label.setFont(new Font("serif", Font.BOLD, 14));
JOptionPane.showMessageDialog(null,label);
