Please help me to find where the problem lies??

Code:

---

public setting(){
cboThn = new JComboBox();
for (Integer i = 1900; i <= 2007;i++){
        cboThn.addItem(i);
}
cboThn.setBounds(280,40,100,20);
cboThn.setActionCommand("thn");
cboThn.addActionListener(this);
}
public void actionPerformed(ActionEvent e){
String strCommand = e.getActionCommand();
if (strCommand.equals("thn")){
JComboBox cb = (JComboBox)e.getSource();
           
Integer year = (Integer)cb.getSelectedItem();
                       
for (Integer k = 2007; k >= 1900; k = k - 12){
                               
                if (k == year){
                        rbo1.setSelected(true);       
                        break;
                }
}
}
}

---

I want to put a value inside the rbo1 (radio button). But it seems like there's a problem in the code above... i can't manage to pass this condition

Code:

---

if (k == year)

---

can anybody here tell me where's my problem lies??

thanks in advance

I think the problem is that you are trying to do an object reference comparison.

Code:

---

if (k == year)

---

is basically saying

Code:

---

if (addressof(k) == addressof(year))

---

which it won't be.

Try using the equals method

Code:

---

if (k.equals(year))

Why are you using Integer in the first place? Use int.
