用你的IDE格式化縮進您的代碼，以便它會更容易修復這些錯誤。 –

再一次，我們不是編譯器。請自己修復你的語法錯誤... – mithrop

這是太多，要求喂勺。即使你是初學者，你也必須知道Ctrl + F。 –

這很奇怪：你有兩個addActionListener（），一個在另一個裏面。我認爲你的錯誤在這裏：你關閉第二個，但不是第一個。與錯誤代碼的

部分：

  b2.addActionListener(new ActionListener() { 
        public void actionPerformed(ActionEvent e) { 
      b1.addActionListener(new ActionListener() { 
        public void actionPerformed(ActionEvent e) {

錯誤應該與此代碼消失：

b2.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
// Code added 
     } 
    }); 
// End of Added code 
    b1.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      t1.setText(""+genericclass.twelveoclockfix + ":" + genericclass.minfixed + " " + genericclass.AMPMtxt); 
      System.out.println(t2.getSelectedItem()); 
      JOptionPane.showMessageDialog(Frame1, "Le 9gag army waz h3r3!"); 

     }});
