User Input with a Do Loop
Alright, so I'm trying to code a program that will have the user input a collection of names and scores and allow them to calculate the highest and second highest scores. The two main questions I have are as follows:
CODE:
package homework7;
import java.util.Scanner;
public class ScoreCalculator {
public static void main(String[] args) {
int i = 0;
Scanner keyboard = new Scanner(System.in);
System.out.print("Please enter the number of students: ");
int count = keyboard.nextInt();
keyboard.nextLine();
do {
i++;
System.out.print("Please enter score number " + i + ": ");
int score = keyboard.nextInt();
keyboard.nextLine();
} while (i <= count);
}
}
- How can I change it to "Please enter name and score number" in the do loop and still extract only the int value despite the fact that a String is also being entered?
- How can I store each int the user inputs into a separate variable within the do loop, and then extract those values and use them at the end to calculate the two highest scores?
Please keep it simple - this is for a class and we aren't very in depth yet. That means no arrays, no separate classes, no files or lists.
Re: User Input with a Do Loop
To see how to use the Scanner class, write a small simple test program and try using different combinations of the next... methods and by entering different combinations of data before pressing Enter.

The best way would be to use an array and change the index to the array every time you store something in it.

As I said, we haven't covered arrays yet, so I need a solution that is more complicated, but not as in depth.
Also, not really sure what you were suggesting at first - care to elaborate, please?

Scratch that, I figured that part out. Still need help on the storing of multiple scores, though.
Re: User Input with a Do Loop
Do you only need to save the two highest scores and none of the others? Then you will only need two variables to save those values in.
