JAVA - isSelected（）から戻ることができません

Question

私はこのコード部分をここに持っていますが、私がプログラムを起動するときはいつも左脳だけになります。私は1つまたは他のボックスをチェックしても。 [OK]を

chckbxMusic = new JCheckBox("Music"); 
    chckbxMusic.addChangeListener(new ChangeListener() { 
     public void stateChanged(ChangeEvent e) { 
      chckbxMath.setSelected(false); 
     } 
    }); 


    chckbxMusic.setBounds(46, 107, 85, 23); 
    Question_1.add(chckbxMusic); 


    chckbxMath = new JCheckBox("Math"); 
    chckbxMath.addChangeListener(new ChangeListener() { 

     public void stateChanged(ChangeEvent e) { 
      chckbxMusic.setSelected(false); 
     } 
    }); 
    chckbxMath.setBounds(243, 107, 128, 23); 
    Question_1.add(chckbxMath); 

    if(chckbxMusic.isSelected()) brain_right++; 
    else brain_left++;

は多分完全なコードは、私はそれを少し書き換えるが、結果は常に両方の変数のための0 ..です もう少しを助けることができます？
