java format 2 decimal places

To format a number with two decimal places in Java, you can use the DecimalFormat class of the java.text package.

Here's an example of how to use the DecimalFormat class to format a number with two decimal places:

import java.text.DecimalFormat;

public class Main {
  public static void main(String[] args) {
    double number = 123.4567;

    // Create a DecimalFormat object with two decimal places
    DecimalFormat df = new DecimalFormat("#.00");

    // Format the number with two decimal places
    String formattedNumber = df.format(number);

    System.out.println(formattedNumber); // prints "123.46"
  }
}

This code creates a DecimalFormat object with a pattern that specifies two decimal places (.00). The format() method of the DecimalFormat object is then used to format the number with two decimal places.

You can use a similar approach to format a number with any number of decimal places, by specifying the appropriate pattern. For example, to format a number with three decimal places, you can use the pattern ".000".
