Am using JTextField for get average.It means the average must be start with 0 to 100.so the textfield allow to access the 0 to 100 only.If I give 101 means the value don't added in the textfield.how to set the condition for this problem?
You have to use KeyListener where you can do the validation.
For example
final JTextField myTextField = new JTextField();
myTextField.addKeyListener(new KeyListener() {
public void keyPressed(KeyEvent keyEvent) {
}
public void keyReleased(KeyEvent keyEvent) {
// Here write the comparison logic
if (Integer.parseInt(myTextField.getText()) > 100){
myTextField.setText(""); // Make it blank
}
}
public void keyTyped(KeyEvent keyEvent) {
}
});
You can use KeyAdapter as well. Hope this helps.
