Having problem with simple variable use in another class

Question

I have a variable made by input from my main class file called upperLimit. I have an external class file in which I would like to use the variable created by the input for upperLimit, but I have forgotten how to go about it. The objective of the program is to output all perfect numbers from 1-upperLimit.
This is my main class:
import java.util.Scanner;
public class Lab13aab
public static void main(String args[])
System.out.print("In the range of [1-10000] what will the upper limit be for analysis? ===> ");
Scanner input = new Scanner(System.in);
int upperLimit = input.nextInt();
System.out.println();
checkToSee isItPerfect = new checkToSee();
int numToCheck;
for(numToCheck=1; numToCheck>=upperLimit; numToCheck++)
isItPerfect.analyze();
}and this is my external class which checks to see if an individual number is a perfect number or not:
public class checkToSee
public void analyze()
int total=1;
int factor;
for(factor=2;factor<upperLimit;factor+…
if(upperLimit%factor==0)
total = total + factor;
if(total==upperLimit)
System.out.println(upperLimit + " is a perfect number!");
System.out.println();
}

Hy Why ;-)!
Let me guess... you're both new to Java AND Object Orientation? Because you're code (apart from the fact that it is not working) is purely procedural and has nothing to do with object orientation (at least most of it). Have you programmed in C/C++ before?
