Answer 3

应该不正确哈，楼主要求是按上回车键;这样子的楼主: JButton jb = new JButton();
jb.addKeyListener(监听器);
  
然后在监听器里实现KeyListener（）的相关方法

Answer 4

 tf.addKeyListener(new   KeyAdapter()     
  {   
        public   void   keyPressed(KeyEvent   e)     
        {     
        if   (e.getKeyChar()   ==   13)//KeyEvent.VK_ENTER)   //按键   执行相应操作;   
        {         
        ta.append("\n\r");     
        ta.append(tf.getText());     
        tf.setText("");//记住该数据后，清空窗口   
        }   
          
        }   
        });
