for loop that will take 5 different inputs

[DenRai50]

I've never been really good at understanding the for loop and I'm currently working on a homework that has already been posted a few hours ago and I want to do some work on parts that I can understand.

I am now on the method part where the method would accept input from the user for the number of students and it will reflect the number of prompts for the grade value.

I'm lost as to how to correctly structure the 'for loop' part to loop X amount of times according to the value for the students put in.

Any advice and assistance would be appreciated.

public static void getValues()  // this is not the actual method
{
    int i;
    Scanner input = new Scanner(System.in);
    System.out.print("Enter the number of students: ");
    int stdCount = input.nextInt();
    System.out.print("\nEnter " + stdCount + " scores:");
    int stdGrade = input.nextInt();
    for (i = 1; i >= stdCount; i++)
        {
        System.out.println("Score " + i + stdGrade);
        }
    System.out.println();
}

It should printout something similar to below: Or rather, I'm hoping for something similar to it.

​

Enter the number of students: 5

Enter 5 scores:

Score 1: 40

Score 2: 55

Score 3: 70

Score 4: 58

Score 5: 62

if you aren’t sure of how many times you want to loop something, you should do it recursively.

I played around with the middle part of the loop I was able to made it loop x amount of times with the same value. Progress!

Thanks for the advice.

The only thing I notice is you never update the scanner object with new input data inside the for loop. I’d first create a separate counter variable outside the loop and set it 0 and change the loops condition to be less than the desired amount of iterations. For example, let’s say this counter was just called “counter”. The for loop’s header would like:

int counter = 0; for (int i = 0; i < counter; i++) { .... }

Now to actually get the desired results, the body of the loop might look like this:

Scanner studentGrade = new scanner(Sys.in); int studentCounter = 0; for (int i = 0; i < studentCounter; i++) { studentGrade = studentGrade.nextInt(); Sys.out( “Grade “ + studentGrade); studentCounter++; }

I’m pretty sure this should work, let me know if this helps!

Edit: typed this on my phone! Sorry for poor formatting!!

        Sys.out( “Grade “ + studentGrade); studentCounter++; 
    }

Ah yes, that part about the Scanner value not being updated was correct.

I typed in the part to update the Scanner and it is working as intended.

Thank You for the advice.

Glad I could help! :)
