I have a JFrame with a text field inside it. When I run the program, the JFrame appears normally. In my program, I have repeatedly asked the JFrame and text field to requestFocus. However, when I click on another window, the JFrame loses focus for a second but regains it again. However, when I type, the letters don't come in the text field.
How can I make it so whenever I type, the text should only appear in the text field.
