Get string size in Java (no graphics object available)

I'm trying to write an application that needs to draw many strings using the graphics2d class in Java I need to get the size of each string object (to calculate the exact location of each string)

When I try to create my own object:

FontRenderContext frc = new FontRenderContext(MyFont.getTransform(),true,true)

Then I get the string boundary. I always get different sizes when I use graphics2d in the paint () method When getfontrendercontext() method gets fontrendercontext The difference is small (about 1e-3), but I don't know why there is any difference?

But is there a better and safer way to get the size of a string?

Thnx any help in advance!

Solution

Try to have a class with fontmetrics; The stringwidth method returns the size of a string

JComponent c = getSomeKindOfJComponent();
FontMetrics fm = c.getFontMetrics(c.getFont()); // or another font
int strw = fm.stringWidth("My text");
