Java Print Double With 2 Decimals

Last Updated : Mar 11, 2024

In this article we will show you the solution of java print double with 2 decimals, usually, when working with numeric values, we need to put them in a special format, such as a fixed number of decimal places.

We will explore different ways to do this and understand the main points. By the end of this tutorial, you will be able to correctly format and print two integers and two values in a Java program.

To solve this problem, we will use the DecimalFormat class available in java.lang.

package. This class provides several methods for formatting numeric values, including combinations with special numeric values.

Step By Step Guide On Java Print Double With 2 Decimals :-

```import java.text.DecimalFormat;
public class DoubleFormatterExample {
public static void main(String[] args) {
double number = 3.14159;
DecimalFormat decimalFormat = new DecimalFormat("#.00");
String formattedNumber = decimalFormat.format(number);
System.out.println("Formatted number: " + formattedNumber);
}
}
```
1. First we need to import the DecimalFormat class of the java.text package.
2. This class provides the necessary methods for formatting numbers. "import java.text.DecimalFormat;" We add the import statement. at the beginning of the rules.
3. In the 'key' method, we define two variables named 'number' and assign the value '3.14159' as an example. You can replace this value with any double you want. This variable represents the number we want to format and print.
4. Next, we create an instance of the 'DecimalFormat' class named 'decimalFormat'. We pass the "#.00" template as a parameter to the constructor. The pattern "#.00" indicates that we want to format the number as two decimal places.
5. The '#' symbol represents a number and the '0' symbol represents a desired number. It is important to note that the.
6. Model can be modified to suit different needs. For example, if you want to display a three-digit number, you can use the pattern "#.000". If you want to display at least two numbers even if they are zero, you can use the "" # pattern.
7. We use the 'format' method of the 'decimalFormat' instance to format the 'number'. and send a formatted number String representation.
8. In our example, the 'format' method changes 'number' to the string '3.14'
9. Finally we print the formatted code using 'System.out'.write a description. A formatted "3.14" number is displayed in the console.
10. It is important to note that the 'format' method returns a string representation of the formatted number, not the actual value.
11. If the original value needs additional calculation or processing, it must be reserved before formatting.

Conclusion :-

In this tutorial, we learned how to print two integers and a double value in Java.

We achieve this by using the DecimalFormat class, which allows us to specify the desired format.

Using the "#.00" pattern, we ensure that the double value is properly rendered with two decimal places.

Note that the DecimalFormat class provides many optional features such as group separation and handling positive/negative numbers.

You can now safely type and print two values with two numeric fields in your Java programs.

I hope this article on java print double with 2 decimals helps you and the steps and method mentioned above are easy to follow and implement.
