Question

TestScores . SIZE: int //size of the array scores: int [ 1 estScores findMax ( ) : int findMin ) int findScore (value: int): bool res(): int Write the constructor method. It fills the array with random number from 0-100. Find below the code to get your started 1. public TestScores () Random rand -new Random); for (int i-0 i<SIZE i+) socresi] -rand.nextInt (101); Finding the maximum value in an array. Write the method findMax. It returns the maximum value in the array Finding the minimum value in an array. Write the method findMin, It returns the minimum value in the array 4 greater or equal to 90. This is an example of linear search Write the method countScores. The method returns the number of exams where the score is Write the method called findScore that accepts one int value. The method should check if the value exists in the array and if it does it returns true. Otherwise the method should return false
