How to find intersection values of two Arrays
This is the third solution to find the intersection of two Arrays of integers. This program uses functional interface with single abstract method, and implementing by using lambda expression. The lambda expression accepts two arrays of integers data type. The internal logic is comparing each value of the first array with each of value of…
