distinct in Java

 distinct() in java

• distinct() is used to get distinct (different) values.
• A list may contain duplicate values, and you want to list the different values, then distinct() will be used.

distinct Java program:

import java.util.*;

import java.util.stream.Collectors;

public class Test {
   public static void main(String args[]) {
      List<String> keywords = Arrays.asList("email", "email", "EMAIL desk", "ABCDE");
      List<String> distinct = keywords.stream().distinct().collect(Collectors.toList());
      System.out.println(distinct);

      List<Character> chars = Arrays.asList('7', '1', '1', '2', '3', '4', '6', '4');
      List<Character> distinctChars = chars.stream().distinct().collect(Collectors.toList());
      System.out.println(distinctChars);
   }
}

Output:
remove duplicates in list

Observe, by using distinct we removed duplicates from list.
