round off to 2 decimal places in java code example

Example 1: java round double to 2 decimal places

import java.math.RoundingMode;
import java.text.DecimalFormat;

public class DecimalExample {
    private static DecimalFormat df = new DecimalFormat("0.00");
    public static void main(String[] args) {
        double input = 1205.6358;
      
        System.out.println("salary : " + input);
      
        // DecimalFormat, default is RoundingMode.HALF_EVEN
        System.out.println("salary : " + df.format(input));      //1205.64
        
        df.setRoundingMode(RoundingMode.DOWN);
        System.out.println("salary : " + df.format(input));      //1205.63

        df.setRoundingMode(RoundingMode.UP);
        System.out.println("salary : " + df.format(input));      //1205.64
    }
}

Example 2: round off java 2 decimal places

class round{
    public static void main(String args[]){

    double a = 123.13698;
    double roundOff = Math.round(a*100)/100;

    System.out.println(roundOff);
}
}

Example 3: java round 2 decimal places

Math.round(input * 100.0) / 100.0;

Example 4: java round to 2 decimal

class round{
    public static void main(String args[]){

      double a = 123.13698;
      double roundOff = Math.round(a*100)/100;

      System.out.println(roundOff);
	}
}
