how to point cursor on the 1st text field in a jframe

I have created a JFrame which is taking some inputs from the user. This form contains some JTextFields. I want to point the cursor to the 1st text field in the frame. how do i do it?
Currently, user needs to select the field first and then enter the data.

The mouse cursor or the text cursor? For the latter use requestFocusInWindow()

i mean text cursor

So use requestFocusInWindow()

somethingField.requestFocus();
