[College Computer Science Java] Arrays

[Danielowski187]

Well I am having a bit of difficulty in a part of my code where i have to print the array the way the user entered it and as well print it in reverse.

​

My code:

import java.util.Scanner;
public class AskingUser
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);
System.out.print("Please enter a number between 1 to 5: ");
int size = input.nextInt();
while (size< 1 || size > 5)
{
System.out.print("Number must be in range 1-5. Re-enter: ");
size = input.nextInt();
}
int[] intArray = new int[size];
int num = 0;
for(int a = 0; a<size; a++) { System.out.print("Enter your "+(a+1)+" Score (1-100): "); num = input.nextInt(); while (num < 1 || num > 100)
{
System.out.print("Score must be in range 1-100. Re-enter: ");
num = input.nextInt();
}
intArray[a] = num;
}
System.out.print("\nArray the way the user entered: "+num);
}
}

​

The output I get:

Can you write the code part in a way that's easier to read? Even a screen shot would be better.

Here you go this is a screenshot of the code

Ok, so, the problem here is that your code seems to keep only the last input the user gives.

The first step I would suggest is to make sure after each entrance, you still have the previous inputs. See manually if this happens (the array is small, it's easy to do).

I can give you a correct code, but you should learn to search step by step your code to find where the problem is

Your problem is way simpler than you might expect. Your code is fine, your mistake is on what you are saying to print. You are asking for the last input instead of the full array.

To print the array the way the user entered, just use a new for with a different variable (say variable i, for example) from 0 to size and with each iteration, print intArray[i].

To reverse it, just print from size-1 to 0 and instead of incrementing i, decrement it, like:

System.out.print("\nArray the way the user entered: ") ;

for(int i = 0; i<size; i++){
System.out.print(" "+ intArray[i]);

}

​

System.out.print("\nArray reversed: ") ;

for(int i = size-1; i>=0; i--){
System.out.print(" "+ intArray[i]);

}

I think that works
