Write a Java program to find the common elements between two arrays

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Arrays; 
public class Javaexcercise {
public static void main(String[] args) 
    {
      int[] array1 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
      int[] array2 = {11, 10, 12, 13, 14, 2, 4, 5};
 
       System.out.println("First Array : "+Arrays.toString(array1));
       System.out.println("Second Array : "+Arrays.toString(array2));
 
 
        for (int i = 0; i < array1.length; i++)
        {
            for (int j = 0; j < array2.length; j++)
            {
                if(array1[i] == (array2[j]))
                {
 
                 System.out.println("Common element : "+(array1[i]));
                 }
            }
        }
 
    }
}

Result:

First Array : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Second Array : [11, 10, 12, 13, 14, 2, 4, 5]

Common element : 2

Common element : 4

Common element : 5Common element : 10
