How to Format a Double value to 2 Decimal places in java

To format a double value to two decimal places in Java, you can use the DecimalFormat class or String.format() method. Here are two common approaches to achieve this:

  • Using DecimalFormat:
import java.text.DecimalFormat; public class FormatDouble { public static void main(String[] args) { double number = 123.456789; // Replace this with your double value // Create a DecimalFormat object with the desired format DecimalFormat df = new DecimalFormat("0.00"); // Format the double value to two decimal places String formatted = df.format(number); // Print the formatted value System.out.println(formatted); // Output: "123.46" } }
  • Using String.format():
public class FormatDouble { public static void main(String[] args) { double number = 123.456789; // Replace this with your double value // Format the double value to two decimal places using String.format() String formatted = String.format("%.2f", number); // Print the formatted value System.out.println(formatted); // Output: "123.46" } }

In both examples, the %.2f format specifier is used to format the double value to two decimal places. You can replace the number variable with your own double value that you want to format.
