I need the answer in Java format

2. (50 points) Write a method that accepts two arrays of integers as parameters, concatenates them, and returns the result. In other words, it creates a new array big enough to store all of the elements in the first parameter and all of the elements in the second parameter combined, and then copies all of the elements from those two arrays into the new one. It should return the concatenated array For example, suppose that the first parameter was [1, 4, 91 and the second was (3, 7 Then we would return the array (1, 4, 9, 3, 7h The Java libraries contain methods that would do most of this for you, but solve the problem by manually creating the new array and copying elements into it
