Format integer values with java.text.DecimalFormat

Here, we are using the DecimalFormat class in Java to format integer value, which is the java.text.DecimalFormat package.

Let us take the following format: DecimalFormat("0.######E0") and use the format() method for this purpose −

new DecimalFormat("0.#####E0").format(5089)
new DecimalFormat("0.#####E0").format(608)

Since, we have used DecimalFormat class in Java, therefore importing the following package in a must −

import java.text.DecimalFormat;

The following is an example −

Example

 Live Demo

import java.text.DecimalFormat;
public class Demo {
   public static void main(String[] argv) throws Exception {
      System.out.println(new DecimalFormat("0.#####E0").format(387979));
      System.out.println(new DecimalFormat("0.#####E0").format(29797));
      System.out.println(new DecimalFormat("0.#####E0").format(49788));
      System.out.println(new DecimalFormat("0.#####E0").format(5089));
      System.out.println(new DecimalFormat("0.#####E0").format(608));
      System.out.println(new DecimalFormat("0.#####E0").format(20));
   }
}

Output

3.87979E5
2.9797E4
4.9788E4
