Java program to find the common elements in two integer arrays

Program to find common elements in two array elements in java

// This program will find common elements from the integer array.

import java.util.Arrays;

public class ExArrayCommonInteger
{
	public static void main(String[] args) 
	{
		// take default integer value.
		int[] array1 = {1993,1995,2000,2006,2017,2020};
		int[] array2 = {1990,1993,1995,2010,2016,2017};

		// print the entered value.
		System.out.println("Array1 : "+Arrays.toString(array1));
		System.out.println("Array2 : "+Arrays.toString(array2));


		for (int i = 0; i < array1.length; i++)
		{
			for (int j = 0; j < array2.length; j++)
			{
				if(array1[i] == (array2[j]))
				{
					// return common integer value.
					System.out.println("Common element is : "+(array1[i]));
				}
			}
		}
	}
}

Output

    Array1 : [1993, 1995, 2000, 2006, 2017, 2020]
    Array2 : [1990, 1993, 1995, 2010, 2016, 2017]
    Common element is : 1993
    Common element is : 1995
    Common element is : 2017
