ICSE Java Programming Array of Numbers 2022 Q4 SPECIMEN PAPER Solved

Question 4

Define a class to declare an array of size 20 of double datatype, accept the elements into the array and perform the following:

Calculate and print the sum of all the elements.

Calculate and print the highest value of the array.

Python Code (Without using class)

_array = []

array_size = 20

max_element = 0.0

sum = 0.0

print("Enter the elements in the array:")

for i in range(array_size):

    print("Enter the element at the position:",(i+1))

    _array.append(float(input()))

    sum += _array[i]

    if max_element < _array[i]:

        max_element = _array[i]

print("Sum of all the elements is ",sum)

print("Maximum element in the array ",max_element)

JAVA CODE
