Question

Please write a java program 

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.

Sample Outpu

What is the size of the array? 3

Give me 3 numbers. 10 20 15

10: !MULT15: !MULT20

20: !MULT15: MULT20

15: MULT15: !MULT20

Answer 1

import java.util.Scanner;
public class Main{
        // this function checks if
        // a number is divisible by 15, 20  
        public int checkArray(int n){
                int status=0;
                if(n%15==0)
                        status+=1;
                if(n%20==0)
                        status+=2;
                
                return status;
        }

                Main obj=new Main();

                System.out.print("Give me "+n+" numbers. ");
                // take input of n numbers
                for(i=0;i<n;i++)

                //check if each number is divisible 
                // by 15 or 25
                // call checkArray() in each iteration
                for(i=0;i<n;i++){
                        if(obj.checkArray(number[i])==0)
                                System.out.println(number[i]+": !MULT15:!MULT20");
                        else if(obj.checkArray(number[i])==1)
                                System.out.println(number[i]+": MULT15: !MULT20");
                        else if(obj.checkArray(number[i])==2)
                                System.out.println(number[i]+": !MULT15: MULT20");
                        else
                                System.out.println(number[i]+": MULT15: MULT20");
                }
        }
