Re: Calling a method

Sorry, I was having problems with my internet, but here is my code:

import java.util.Scanner;

public class IntergerSet
{
    private static final int SIZE = 101;
    private boolean[] arraySet = new boolean[SIZE];

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

    //overloading constructor
    public IntergerSet(int j)
    {
      if(validEntry(j))
      insert(j);
    }

    //check valid entry not over 100.
    private boolean validEntry(int k)
    {
        return k>=0 && k<=SIZE;
    }

    //Getting input from the user.
    public void inputSet ()
    {
        Scanner input = new Scanner (System.in);

     int value;
     boolean arraySet[] = new boolean[100];
     do
     {
     System.out.println("\nPlease enter a value or -1 to finish: ");
     value = input.nextInt();
     if(validEntry(value))
             arraySet[value] = true;
            else
             System.out.println("\nInvalid value");
     }while(value != -1);
    }

    //Finding the union of two sets
    public void union(boolean other[])
    {
     boolean res[] = new boolean [SIZE];

     for(int i=0; i<SIZE; i++)
     if(arraySet[i]==true||other[i]==true)
     res[i] = true;
     arraySet = res;
    }

   //Finding the intersection of two sets
    public void intersection(boolean other[])
    {
    boolean res[] = new boolean [SIZE];

        for(int i=0; i<SIZE; i++)
         if(arraySet[i]==true&&other[i]==true)
     res[i] = true;
         arraySet = res;
    }

    //Inserting a value to the set
    public void insert(int other)
    {
        if(validEntry(other))
        {
            System.out.printf("\nYou add %d ", other);
            arraySet[other]=true;
        }
        else

            arraySet[other]=false;
        }
        else
            System.out.print("\nInvalid delete attempted\n");
    }

    //Prints the sets in a string.
    public String toSetString()
    {
        String setString = "{ ";
        boolean empty = true;

        for(int s=0; s<SIZE; s++)

                empty = false;
            }
        }
        if(empty)
