List<Integer> common = new ArrayList<Integer>();
System.out.printf("Enter n number Arr1: ");
int x1 = x.nextInt();
System.out.printf("Enter n number Arr2: ");
int x2 = x.nextInt();

System.out.printf("Enter Arr1: ");
for(int i = 0; i < x1; i++)
System.out.printf("Enter Arr2: ");
for(int i = 0; i < x2; i++)
for(int e: l1)
if(l2.contains(e))
for(int e: common)
System.out.println("Common: "+e);
}
}
```

OUTPUT:

Input:
Enter n number Arr1: 3
Enter n number Arr2: 2
Enter Arr1: 12 25 36
Enter Arr2: 36 66
Output:
Common: 36

Input:
Enter n number Arr1: 4
Enter n number Arr2: 3
Enter Arr1: 22 25 101 25
Enter Arr2: 63 101 22 0
Output:
Common: 22
Common: 101

Input:
Enter n number Arr1: 1
Enter n number Arr2: 1
