Find The Matching Elements Of One Array To Another Array In Java

Lets find an element of first array in another array. so lets start from array 1 in which we taking some elements and than take some elements in array 2 . now start for loop for first array and inside for loop take another for loop to iterate second arrays elements and in first loop we will iterate elements of first array. now take the if condition inside second for loop to check where elements of first array are same or not as element of second array if elements are same than we will print that element.





import java.util.*;
import java.lang.*;
import java.io.*;


class Test
{
public static void main (String[] args) throws java.lang.Exception
{
int arr[]={2,4,5,6,7,8};
int arr1[] ={9,12,65,6,5,98,7};
for(int i=0;i<arr.length;i++)
               {
for(int j=0;j<arr1.length;j++)
                       {
if(arr[i]==arr1[j])
                               {
System.out.print(arr1[j]+" ");
}
}
}
}
}


Output : 5  6   7
