看看这段代码有什么毛病

Question

 if(j==2)
                      {
                          if(resultLabel4.getText()==resultLabel5.getText())
                          {
                              startButton.setEnabled(false);
                              stopButton.setEnabled(false);
                          }    
                      }
                       else if(j==3)
                       {
                          if((resultLabel6.getText()==resultLabel5.getText())||(resultLabel6.getText()==resultLabel4.getText())) 
                          {
                              startButton.setEnabled(false);
                              stopButton.setEnabled(false);
                          }
                       }
当Label的Text相同时也不执行startButton.setEnabled(false);
                              stopButton.setEnabled(false);这是怎么回事，请教高手

字符串比较使用equals()方法,不是使用==
