textfield for integer or string

Hi experts,

I need code for the following:
I have a textfield and two buttons. One button should be expect an integer from the text field (between 1-99) and when pressed it changes an integer variable.
the other button should expect a String and then change the "name" variable

thanks

Sorry:

button1.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent evt) {
try {
integerVariable = (Integer.valueOf(textField.getText())).intValue();
} catch (NuberFormatException ex) { }
}
});

Allow me to correct:

1)
void jButton4_actionPerformed(ActionEvent e)
{
try { // <<<<<<<< try/catch needed
int thisVal = Integer.parseInt(jTextField1.getText());
if( thisVal >= 1 && thisVal <= 99) // <<<<<< && instead of ||
myValu = thisVal;
} catch (NumberFormatException ex) {
}
}

Remark: I don't see the added value compared with my previous comment

2)
If you want to check if the string only contains A-Z, a-z, spaces and dots, you can better do this:

void jButton5_actionPerformed(ActionEvent e) {

if ( jTextField1.getText().matches("([A-Za-z \\.])+?") )
name = jTextField1.getText();
}

That's the power of regular expressions!
