Need some pointers

[nestensity]

I'm trying to create a program that prompts the user to input the amount of students and their score and then prints it out. However im stuck at slots.get(i).inputData(); as i get

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
	Cannot invoke inputData() on the primitive type int

	at GradeBook.main(GradeBook.java:52)

some help would be greatly appreciated

import java.util.ArrayList;
import java.util.Scanner;


public class GradeBook {
public int sid;
public int q1;
public int q2;
public int q3;
public int q4;
public int q5;
public int response;



public GradeBook(int sid, int q1, int q2, int q3, int q4, int q5){
inputData();
}
 	public void inputData(){
 		Scanner in= new Scanner(System.in);
		System.out.println("Enter 4 digit student ID");
		sid = in.nextInt();
		System.out.println("Enter score for quiz one");
		q1 = in.nextInt();
		System.out.println("Enter score for quiz two");
		q2 = in.nextInt();
		System.out.println("Enter score for quiz three");
		q3 = in.nextInt();
		System.out.println("Enter score for quiz four");
		q4 = in.nextInt();
		System.out.println("Enter score for quiz five");
		q5 = in.nextInt();
		ArrayList<Student> info= new  ArrayList<Student>();

		 info.add(new Student(sid, q1,q2,q3,q4,q5));
		 int a= info.size();
		 for(int x= 0; x<=a;x++){
			 System.out.println(info.get(a));
		 }
		 }	 
 	}
	public static void main(String[] args) {
	
		Scanner in= new Scanner(System.in);
 		System.out.println("How many students do you wish to add? ");
		int response = in.nextInt();
		ArrayList<Integer> slots= new ArrayList<Integer>(response);
		 for(int i=0; i<=response;i++){
			 slots.get(i).inputData();
		 }
		
		
		
		}

That's strange. Line 52 in the error message is blank in the code you posted.
What does the method slots.get(i) return? Is it an object with a method: inputData()?

Break up the compound statement into separate parts and println() the results of each part. Compound statement has more than one . in it

The erroneous line is Line 49 in the post, Your "slots" variable inside the main() method is an ArrayList of integers. So slots.get(i) returns an Integer object, and last I checked the javadocs of Integer class did not have any such method.
