Hey! If you just need a quick and easy way to format your double with two decimal places, you can use String.format(). It’s simple and works well for display purposes:
double value = 4.0;
String formatted = String.format("%.2f", value);
System.out.println(formatted); // Output: 4.00
This method ensures that your number always has two decimal places, no matter what. It’s a great option when you need java format double functionality for printing or logging.
