Thread: how to adjust the size on a graphic component

So im trying to adjust the size on this graphic component code anyone have any ideas?

public class DisplayComponent extends JComponent
{
	private boolean hasLetter = false;
	private GameEngine game;
 
		public void paintComponent(Graphics g)
		{
			// Recover Graphics2D
			Graphics2D g2 = (Graphics2D) g;
 
			Line2D.Double bottom = new Line2D.Double(100, 500, 600, 500);
			g2.draw(bottom);
			Line2D.Double side = new Line2D.Double(200, 500, 200, 100);
			g2.draw(side);
			Line2D.Double top = new Line2D.Double(200, 100, 450, 100);
			g2.draw(top);
			Line2D.Double hang = new Line2D.Double(450, 100, 450, 150);
			g2.draw(hang);
                        //EVERYTHING BELOW IM TRYING TO ADJUST
		        String newWord = game.getGuessWord();
			g2.drawString(newWord, 350, 600);
 
		}

//EVERYTHING BELOW IM TRYING TO ADJUST

The String newWord contains a string like(_ _ _ _) and what im trying to do is make whatever is in the variable newWorld display on the JFrame, to be bigger font.

See Graphics.setFont. If you wish to just change the current font, you can simply call getFont().deriveFont(fontizeasfloat) and pass that to setfont.

ok here is my new code, yet it still doesnt seem to be changing

		public void paintComponent(Graphics g)
		{
			// Recover Graphics2D
 
			Graphics2D g2 = (Graphics2D) g;
 
			Line2D.Double bottom = new Line2D.Double(100, 500, 600, 500);
			g2.draw(bottom);
			Line2D.Double side = new Line2D.Double(200, 500, 200, 100);
			g2.draw(side);
			Line2D.Double top = new Line2D.Double(200, 100, 450, 100);
			g2.draw(top);
			Line2D.Double hang = new Line2D.Double(450, 100, 450, 150);
			g2.draw(hang);
                        //EVERYTHING BELOW IM TRYING TO ADJUST
			String newWord = game.getGuessWord();
			Font font = getFont().deriveFont(200);//<<<<<<<<<<<<NEW LINE
			g2.setFont(font);//<<<<<<<<<<<<<<<<<<<<<<<<<NEW LINE
			g2.drawString(newWord, 350, 600);
 
		}

Read the API for deriveFont, as I vaguely indicated in my post above to change the font size the parameter must be a float. (eg deriveFont(200f))

Thanks that worked just like how i was wanting it, but why does it work when i just add an "f" at the end of that number. I mean i understood it had to be a float but my understanding was that floats and doubles are relatively the same in the way, only real difference is that float is like a point on a graph by itself. But just putting an "f" at the end? what does that mean? im relatively new to programming so forgive me if it sounds a little naive . Thanks for helping nevertheless

Have you read the API for Font? What are the overloads of DeriveFont and what Type of parameters do they take?
