How to remove the text border in a component?

Question

I have a program in Java and would like to remove these borders that appear in the button text:

(The red edges were in the issue the ones I want to remove are those dark blue ones inside the red ones)

Answer 1

You can remove as the Renan spoke, but will be without the references of phocus to access the buttons with the tab and the space bar for example.

setFocusable(false);

Answer 2

Define Component#setFocusable() with false causes this border around the text to be removed. In fact this is indicative that the component is in focus.

JButton foo = new JButton();
foo.setFocusable(false);
