How do you set a focus on JTextField in Swing?

I created a form using Swing in Java. In the form I have used a JTextField on which I have to set the focus whenever I press a key. How do I set focus on a particular component in Swing?

How do you set focus on textField?

For me the easiest way to get it to work, is to put the component. requestFocus(); line, after the setVisible(true); line, at the bottom of your frame or panel constructor.

Which method is used to set or change the text in JTextField?

The following code creates and sets up the text field: textField = new JTextField(20); The integer argument passed to the JTextField constructor, 20 in the example, indicates the number of columns in the field.

Would Component.requestFocus() give you what you need?
