  • Java 8 introduces for each loop.
  • before that lest see an example of how normal java for each loop.

#1: Java Example program which explain use of for each loop.

  1. package com.instanceofjava.java8;

  2. import java.util.HashMap;
  3. import java.util.Map;

  4. public class ForEachLoop {
  5. /**

  7. * @category interview questions
  8. * Description: java 8 for each loop
  9. *
  10. */
  11. public static void main(String[] args) {
  12. Map<String, Integer> stumarks = new HashMap<>();
  13. stumarks.put("Sai", 65);
  14. stumarks.put("Vamshi", 65);
  15. stumarks.put("Mahendar", 76);
  16. stumarks.put("Muni", 87);
  17. stumarks.put("Manohar", 90);

  18. for (Map.Entry<String, Integer> entry : stumarks.entrySet()) {
  19. System.out.println(entry.getKey() + " marks : " + entry.getValue());
  20. }

  21. }

  22. }

Output:

  1. Muni marks : 87
  2. Vamshi marks : 65
  3. Mahendar marks : 76
  4. Sai marks : 65
  5. Manohar marks : 90

#2: Java Example program which explains the use of for each loop in java 8

  • In the above program we used for each loop to get key value pairs of map.
  • Same thing will be done in java 8 by using stumarks.forEach((k,v)->System.out.println( k + " marks : " + v));
