    Post Java program to format a double value to 2 decimal places

    This code allows you to round a double value to 2 decimal places using DecimalFormat.

    You can increase the decimal places by adding an extra #. For example DecimalFormat("#.###"); rounds to 3 decimal places.

    import java.text.*;
     
    public class DecimalPlaces {
     
        public static void main(String[] args) {
     
            double d = 1.234567;
            DecimalFormat df = new DecimalFormat("#.##");
            System.out.print(df.format(d));
        }
     
    }

    you can also do this,

    public class DecimalPlaces {
     
        public static void main(String[] args) {
     
            double d = 1.234567;
            System.out.printf("%1$.2f", d);
        }

    public void GetTwoDecimal(){
     
            double d = 2.34568;
            DecimalFormat f = new DecimalFormat("##.00");  // this will helps you to always keeps in two decimal places
            System.out.println(f.format(d)); 
    }
