In a try statement in which the exception is caught how do you prevent the program from displaying error messages
This is is program whereby there exiext a button and a textfield , a figure is entered into the textfield , anytime the user presses the button th efolowing procedure is invoked.
I have written a try statement to check if the correct numbers are inputted, i want to stop the system from printing error messages if the try throws an exception pls how do i do this

public void actionPerformed(ActionEvent ae) {
int b=0;
// validate inputs
try {
Integer.parseInt(maxPoints.getText());
}
catch (NumberFormatException e){
JOptionPane.showMessageDialog(null, "the maximum points value must be a number",
"maximum points", JOptionPane.ERROR_MESSAGE);
}

The system, by default, doesn't show any messages when you catch an exception. The only reason the system does in this case is because you tell it to with the call to showMessageDialog(). If you get rid of that method call, then no message will be shown.
