I am drawing 2 Strings which the one include my Name, Middle-name, Surname and the other my Country i am creating them in a paint Component which is located in a Center panel, however, I have tried many different ways and calculations to center that String but no one of them is working correctly with accuracy is their an accurate way ? this is an example of calculations that i have tried so far 

posX=((getWidth()-fm.stringWidth(phrase))/2);
posY= ((getHeight()-fm.getHeight())/2);

  • *"however, I have tried many different ways and calculations to center that String but no one of them is working correctly with accuracy is their an accurate way ?"* - I'd be nice if you could provide a demonstration of it "not working" and contracts that with what you are attempting to achieve – MadProgrammer Nov 07 '17 at 21:11

    Why are you doing custom painting? Use JLabels and an appropriate layout manager. The layout manager will look after centering all the components. – camickr Nov 07 '17 at 21:45

Because text is rendered from the baseline up, you need to adjust the y position to take that into account:

posY = ((getHeight() - fm.getHeight()) / 2) + fm.getAscent();

Otherwise you're centring the text about the baseline, instead of "absolutely"

This is demonstrated in this example

You should also have a look at Font Concepts for more details
