Last update on December 21 2024 09:36:21 (UTC/GMT +8 hours)

Write a Java program to compare two linked lists.

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise24 {
  public static void main(String[] args) {
   LinkedList<String> c1= new LinkedList<String>();
          c1.add("Red");
          c1.add("Green");
          c1.add("Black");
          c1.add("White");
          c1.add("Pink");

          LinkedList<String> c2= new LinkedList<String>();
          c2.add("Red");
          c2.add("Green");
          c2.add("Black");
          c2.add("Orange");

          //comparison output in linked list
          LinkedList<String> c3 = new LinkedList<String>();
          for (String e : c1)
             c3.add(c2.contains(e) ? "Yes" : "No");
          System.out.println(c3);         
     }
}

Sample Output:

[Yes, Yes, Yes, No, No]
