compare jTextField - java

Question

可以比较JTextField的值（字符串）吗？我有一些代码块类似波纹管，所以我的ideia比较（！=或==）这 - pn50.setText(play4b)与，例如，pn50.setText(play5b);

我想避免比较字符串play5b或play4b，原因是PN50根据按钮按下重写

 //card2 
    ActionListener two = new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      if (gr.getCounter1() < 1) { 
       gr.setCounter1(gr.getCounter1() + 2); 
       test1.setIcon(play1b); 
       pn1.setText("Value of card: " + play2b); 
       pn5.setText(play3b); 
       pn50.setText(play4b); 
       arraybtn[2].setText("no Card"); 
       arraybtn[2].setBackground(Color.lightGray); 
      } else { 
       pn5.setText("Only one Card"); 
      } 
     } 
    }; 

感谢

的getText()方法将返回一个JTextBox的文本。使用.equals或.compareTo来比较字符串。
