Write a java program to print intersection elements of both the array

int arr1[] = {1, 2, 2, 1};

int arr2[] = {2};

class Intersection

{

public static void main(String args[])

{

int arr1[] = {1, 2, 2, 1};

int arr2[] = {2};

System.out.println(“Intersection of 2 arrays”);

for(int i=0;i< arr1.length; i++)//i=1; 1<4;

{

for(int j=0;j< arr2.length;j++)//j=0; 0<1

{

if(arr[i]==arr[j])//2==2

{

System.out.println(arr1[i]+ ” “);//2

arr2[j]=-1;//-1

break;

}

}

}

}}
