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?

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.
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?
