Sending data from one class to another

Hi, I want to send the values that the user enters and I am storing
them in several arrays in the IntegerSetTest class. It need to be
sended to the IntergerSet class to find the union, intersection, etc.

Here is IntegerSetTest class:
import java.util.*;
public class IntegerSetTest
{
    public static void main(String args[])
    {
        Scanner input = new Scanner(System.in);
        String inputValue;

        String strArray1[] = new String[100];
        int countInts = 0;
        for(int i = 0; i < strArray1.length; i++)
        {
            System.out.println("Enter integers for set A. (Press any
other key to finish set). ");
            inputValue = input.next();
            try
            {
                Integer.parseInt(inputValue);
                strArray1[i] = inputValue;
                countInts++;
            }
            catch(NumberFormatException ex)
            {
                break;
            }
        }
        int intArray1[] = new int[countInts];
        for(int i = 0; i < countInts; i++)
            intArray1[i] = Integer.parseInt(strArray1[i]);

        String strArray2[] = new String[100];
        countInts = 0;
        for(int i = 0; i < strArray2.length; i++)
        {
            System.out.println("Enter integers for set B. (Press any
other key to finish set). ");
            inputValue = input.next();
            try
            {
                Integer.parseInt(inputValue);
                strArray2[i] = inputValue;
                countInts++;
            }
            catch(NumberFormatException ex)
            {
                break;
            }
        }
        int intArray2[] = new int[countInts];
        for(int i = 0; i < countInts; i++)
            intArray2[i] = Integer.parseInt(strArray2[i]);

        String strArray3[] = new String[100];
        countInts = 0;
        for(int i = 0; i < strArray3.length; i++)
        {
            System.out.println("Enter integers for set C. (Press any
other key to finish set). ");
            inputValue = input.next();
            try
            {
                Integer.parseInt(inputValue);
                strArray3[i] = inputValue;
                countInts++;
            }
            catch(NumberFormatException ex)
            {
                break;
            }
        }
        int intArray3[] = new int[countInts];
        for(int i = 0; i < countInts; i++)
            intArray3[i] = Integer.parseInt(strArray3[i]);

        String strArray4[] = new String[100];
        countInts = 0;
        for(int i = 0; i < strArray4.length; i++)
        {
            System.out.println("Enter integers for set D. (Press any
other key to finish set). ");
            inputValue = input.next();
            try
            {
                Integer.parseInt(inputValue);
                strArray4[i] = inputValue;
                countInts++;
            }
            catch(NumberFormatException ex)
            {
                break;
            }
        }
        int intArray4[] = new int[countInts];
        for(int i = 0; i < countInts; i++)
            intArray4[i] = Integer.parseInt(strArray4[i]);
}

And here is IntergerSet class:
import java.util.Scanner;

public class IntergerSet
{
    private static final int SIZE = 101;
    private boolean[] arraySet = new boolean[SIZE];
    private boolean validEntry(int k)
    {
        return k>=0 && k<=SIZE;
    }

    // No-arguments.
    public IntergerSet()
    {
        for(int i=0; i<SIZE; i++)
            arraySet[i] = false;
    }

    //overloading
    public IntergerSet(int arraySet[])
    {
     //obtain the values of the set that the user enter.
    }

    public IntergerSet union(IntergerSet other)
    {
     IntergerSet res = new IntergerSet();

     for(int i=0; i<SIZE; i++)
     res.arraySet[i] = this.arraySet[i]||other.arraySet[i];
        return res;
    }

    public IntergerSet intersection(IntergerSet other)
    {
    IntergerSet res = new IntergerSet();

        for(int i=0; i<SIZE; i++)
         res.arraySet[i] = this.arraySet[i]&&other.arraySet[i];
        return res;
    }
}

Thanks
