How to Round up to 2 Decimal Places in Java

In this example we will show two methods to round a number to 2 decimal places in Java.

Source Code

1) Using String.format()

package com.beginner.examples;

public class RoundExample1 {

	public static void main(String[] args) {

		double x1 = 0.006;
		System.out.println(String.format("%.2f", x1));
		
		double x2 = 0.002;
		System.out.println(String.format("%.2f", x2));
		
		double x3 = -0.006;
		System.out.println(String.format("%.2f", x3));
		
		double x4 = -0.002;
		System.out.println(String.format("%.2f", x4));
    }
}

Output:

0.01
0.00
-0.01
-0.00

2) Using java.text.DecimalFormat

package com.beginner.examples;

import java.text.DecimalFormat; 

public class RoundExample2 {

	public static void main(String[] args) {
		DecimalFormat  df = new DecimalFormat("######0.00");  

		double x1 = 0.006;
		System.out.println(df.format(x1));
		
		double x2 = 0.002;
		System.out.println(df.format(x2));
		
		double x3 = -0.006;
		System.out.println(df.format(x3));
		
		double x4 = -0.002;
		System.out.println(df.format(x4));
    }
}

Output:

0.01
0.00
-0.01
-0.00
