Write a method that sums all integers above a given threshold (inclusive) in an array. Sample input values: {1,2,3,4,5) and 2 Returned value 2+3+4+5 = 14 Sample input values: {-5, -10, 0, 5, 10), and 0 0 + 5 + 10 = 15 Write a method that calculates the average of all integers above a given threshold (inclusive) in an array. Sample input values: {1,2,3,4,5) and 2 Returned value 2+3+4+5 = 14/4 = 3.5 Sample input values: {-5, -10, 0, 5, 10), and 0 0 + 5 + 10 = 15/3 = 5.0 Write a method that sums all even integers in an array. Sample input values: {1,2,3,4,5) Returned value 2+4 = 6 Sample input values: {-5, -10, 0, 5, 10} -10 + 0 + 10 = 0
