Compact Number Formatting

Compact formatting is introduced in Java 12, where you can put big numbers for decimal, Currency, and percentages to short form or long form for instance 1000 to 1K.

The Below-Given Syntax Shows the Use:

NumberFormat formatter = NumberFormat.getCompactNumberInstance(
   Locale.US, NumberFormat.Style.SHORT);
   System.out.println(formatter.format(1000)
);

Examine the Below Given Example:

ApiTester.java

import java.text.NumberFormat;
import java.util.Locale;

public class APITester {
   public static void main(String[] args) {
      NumberFormat formatter = NumberFormat.getCompactNumberInstance(
         Locale.US, NumberFormat.Style.LONG);

      System.out.println(formatter.format(1000));
      System.out.println(formatter.format(1000000));

      formatter = NumberFormat.getCompactNumberInstance(
         Locale.US, NumberFormat.Style.SHORT);

      System.out.println(formatter.format(1000));
      System.out.println(formatter.format(1000000));
   }
}

Output

1 thousand
1 million
1K
1M
