places the 2 decimal place by using decimal format 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: java 2 decimals

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