您应该创建标签，设置字体，然后用它来创建messageDialog。尝试是这样的：

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);

是否有我应该打电话的任何导入？因为没有一个JLabel当我键入它 – Miki

是的，“javax.swing.JLabel中的”如果你正在使用Eclipse，有一个很好的快捷键“Ctrl + Shift + O”，添加你需要的所有进口： –

还要考虑'的deriveFont （）'。 – trashgod

请参阅How to Use HTML in Swing Components。例如：

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

现在a1将出现在大胆。
