Today I was programming a toString method for a class widely used in a application, using the very useful String.format that provides a C’s like printf formatter.
@Override
public String toString() {

}
%.1f means a float with one digit precision after the dot separator. The code [...]

Here’s a program that lists fonts available in your JVM. You can also set the environment variable JAVA_FONTS to specify the font directory.
import java.awt.GraphicsEnvironment;
public class ListFonts {
public static void main(String args[]){
GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
for(String font:e.getAvailableFontFamilyNames()){
System.out.println(font);
}
}
}
By using pipes you can count how many fonts you have:
java ListFonts|wc -l
On my Ubuntu machine here I got 556 because [...]
