Question

Write in java please

Instructions

• Your goal is to take N integer inputs from the user -- N's value will be given by the user as well.
  • You can assume the user provides a valid value for N, i.e., >0.
• Store the input integers in an array of size N in the order they are provided.
  • These tasks should be done in the main() method.
• Create a new method called checkArray() that will take the previously created array as input from main().
• Decide whether each member of the array is a multiple of 15 and 20 or not.
• And, print the decision in the same way as shown below.
• You can use the code structure given below.
• If you do not follow any of the instructions, you will lose points.

Code Structure

main(){

N = take input from user;

arr = create a N-size array.

populate the array with user inputs.

call the checkArray() method and send arr.

}

checkArray(){

for each array member of arr, check if it is a multiple of 15 and 20 or not.

print the results.

}

Sample Output

• Your output should look exactly like the following; otherwise, you will lose points.

What is the size of the array? 3

Give me 3 numbers. 10 20 15

10: !MULT15: !MULT20

20: !MULT15: MULT20

15: MULT15: !MULT20
