for in while loop and arraylist advanced for

1)my first problem is that i want to make the input in my while loop print out score1,score2,etc until the user inputs a non integer value but i dnt knw wat to put a place of 50 to solve my problem
2)the advanced for loop gives a syntax error that says "incompatible types,reuired int ..found java.lang.object"..and i need to print the value of the total calculations i have done

Code:

---

import java.util.*;
public class Sumcalculator {
   
    public static void main(String[] args)
    {
      ArrayList scores1=new ArrayList();
   
     
      Scanner input=new Scanner(System.in);
     
      System.out.println("TYPE IN THE SCORES OF THE FIRST STUDENT:");
      System.out.print("score 1: ");
      while(input.hasNextInt())
      {
        for(int i=2;i<50;i++)  //i dont know what to write in place of 50!!
        {   
            int stud1=input.nextInt();
            System.out.printf("%s %d%s","score",i,":");
           
           
          scores1.add(stud1);
     
      }
      System.out.print(scores1);
    for(int nums: scores1) //doesnt advanced for loop work for array list?
    {   
      int total=total+nums;
    }
       
  }

Think that is what you are looking for, and no need for the for loop as it will exit on non-integer entries.

thanks a lot bro...it really helped...you wrote the code completely...you are good
