Given the following method, and an one dimensional int array- numbers, if call testMethod(numbers, 5) returns a -1, what information can we obtain from the return value? public static int testMethod (int[] array, int target) { for (int i = 0; i < array.length; i++) == if (array[i] return -1; target) return i; Question 20 (5 points) Provide a method named rowSum which accepts a two dimensional int array as parameter, this method will find the sum of each row and store the result in a one dimensional int array. By the end, this method will return the result array. Hint: //initialize an one dimension array to store the result // for each row //row sum<-0 // for each col of this row //add element to row sum //store row sum in array //return array Question 21 (4 points) Provide a method named isIncreasing which accepts an one dimensional int array as parameter. It will check and return whether the elements stored in this array is sorted in increasing order or not. Return true for yes and false for no. (Hint: Use for loop to check if array[i]<array[i+1] is always true for all valid index i and i+1).
