How to get the focus to a specific field in GUI in Java

When working with Graphical User Interfaces(GUI) the main thing you should keep in your mind is user friendliness. Think about an example that you try to get some details from the user for different text fields. When the user hits the save button we first have to validate the fields as to check the correctness of data. Then, we found that one data in a text field is incorrect. So we have to send a message to the user indicating that there is an error in that particular field. What if we can focus that text field to the user. Is it very friendly, right? It’s just a simple thing. Try this out

//code for the action performed event of the save button
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
// save the details

private booleanvalidateTextFields(){
JOptionPane.showMessageDialog(null, "The data you entered is incorrect", "Warning", 1);
return false;
