Hi,
i m beginner and working on my assignement write code of a weight calculation base on person's heaight..

code have 2 JRadio Button and 1 JSlider
JR Buttons:
"Male"
"female"
change event & action command set on both buttons.
and actionlistener. on slider.

here is a bit of both part of code for buttons & slider:

public void actionPerformed(ActionEvent ae) {

if("Female".equals(ae.getActionCommand())) {
if(f.isSelected() ); // f is name of JRadio buttom "Female" is setActionCommand("Female"), m is name of male button
jb2 = f.getText();

}
} // end of action performed

public void stateChanged( ChangeEvent evt )
{

JSlider source = (JSlider)evt.getSource();

if ( !source.getValueIsAdjusting( )) {
sl = source.getValue();
h = sl*sl;
} // End of if line 6

// jb2 (string reference from change event)

if(evt.getSource() ==jb2){
h3 = h/30;
ans2 = h3 +"";
textA.setText(ans2);

}else {
h2 = h/28;
ans = h2 +"";

jb2 is string where store the button value(name)
sl is integer and getting value from slider
