The returned array should be the right-size, meaning that all of its elements are used to store an even int found in the parameter. Thismeans that the returned array may have anywhere from zero to n elements, where n is thelength of the formal parameter array.2) Write method, compress, which accepts an array of int and returns an array containing thesums of each pair of integers in the array parameter. So, if arr is the array parameter, then thefirst element of the returned array contains the sum arr[0] and arr[1], the second element ofthe returned array contains the sum of arr[2] and arr[3], etc. If the array parameter has an oddnumber of elements, then the last element of the returned array contains the last element ofthe array parameter.3) Write method, union, which accepts two arrays of int as sets. This means that neither arraycontains duplicates within them. This method returns an array that is the union of the twoparameter sets (arrays). The union is also a set and therefore cannot contain duplicates. Thismethod must make sure that if the two parameter sets have a common element value, thenthat value should appear in the union set (array) only once. The union array returned should beright-sized.4) Write method, shuffle, which accepts an array of int, creates a copy of the formal parameter,shuffles the copy, then returns the copied, shuffled array, leaving the formal parameterunchanged. Shuffling is a process of swapping each element of array with another elementrandomly chosen from the array.5 BONUS Pts: For testing the shuffle method have main call shuffle, repeatedly having itshuffle its previously returned array until the returned (shuffled) array is identical (equal) tothe original array that was first shuffled. So, your loop would contain a statement like thefollowing:shuffledArrayshuffle( shuffledArray );1,903DECétvLO
