// The arguments to all these format methods consist of
// a format code String and 1 or more arguments.
// Each format code consists of the following:
// % - code lead-in
// N$ - which parameter number (1-based) after the code
// N - field width
// L - format letter (d: decimal(int); f: float; s: general; many more)
// For the full(!) story, see javadoc for java.util.Formatter.
Formatter fmtr = new Formatter();
Object result = fmtr.format("%1$04d - the year of %2$f", 1951, Math.PI);
System.out.println(result);
// A shorter way of doing things. But this
// way you must provide the newline delimiter
System.out.format("%1$04d - the year of %2$f%n", 1951, Math.PI);
// So is this
System.out.printf("%1$04d - the year of %2$f%n", 1951, Math.PI);
// Format doubles with more control
System.out.printf("PI is about %1$4.2f", Math.PI);
