try this....

DecimalFormat df = new DecimalFormat("#.##");
df.format(3.1426384473);

Or if u just wanna print then u can use this also...

System.out.printf("%.2f",d); //d is your number

public static double round(double value, int places) {
    if (places < 0) throw new IllegalArgumentException();

    long factor = (long) Math.pow(10, places);
    value = value * factor;
    long tmp = Math.round(value);
    return (double) tmp / factor;
}
