I have an application that extends a Frame. Then, it'll display a few lines of text using: Font f = new Font("Arial", Font.PLAIN, 10); g.setFont(f); g.drawString("Test|great Yes ^.", x, y + 10); Now what happens is that the text doesn't fit in the box around. E.g. I'm expecting the text to fit in [x,y]-[x+width, y+10] (don't care abou...

I think it should be in the init() method, but netbeans does not allow me to change that part of the code. This is the code I added for the image: //these four lines I added to...
