Re: Calling a method

Well here is my code again:

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
            System.out.print("\nInvalid insert attempted\n");
    }

    //Deleting a value from the set
    public void delete(int other)
    {
        if(validEntry(other))
        {
            System.out.printf("\nYou delete %d ", other);
            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++)
        {
            if(arraySet[s])
            {
                setString = setString + s + " ";
                empty = false;
            }
        }
        if(empty)
            setString = "---";
        setString = setString + " }";
        return setString;
    }

    //Checks if the sets are equal
    public void isEqualTo(boolean other[])
    {
        for(int t=0; t<SIZE; t++)
            if(arraySet[t] != other[t])
            return false;
        return true;
    }
}

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

        boolean arraySetA[] = new boolean[101];
     boolean arraySetB[] = new boolean[101];
     boolean arraySetC[] = new boolean[101];
     {
        final int[] init = {6, 7, 9, 50, 69, 86};

           arraySetC[init[i]] = true;
     }
        boolean arraySetD[] = new boolean[101];
     {

     }

        int i, j;

        }

        System.out.println("Welcome to the Integer Set\n");

     System.out.println("This program is going to find the union or "
+

     "or insert an element and check if the sets are equal.");

        IntergerSet set = new IntergerSet();

        System.out.println("\n\nIf you want to add a value to the set
press 'a': ");
        String adding = input.next();
        if("a".equalsIgnoreCase(adding))
    {

        System.out.print("\nEnter the value to be added: ");
         int addValue = input.nextInt();
         set.insert(addValue);
    }

        System.out.println("\n\nIf you want to delete a value from the
set press 'd': ");
        String deleting = input.next();
        if("d".equalsIgnoreCase(deleting))

\n");
        System.out.print("\nEnter the value to be deleted: ");
         int deleteValue = input.nextInt();
         set.delete(deleteValue);
    }

    System.out.print("Enter 'u' to find the union\nEnter 'i' to find the
intersection\n" +
        "Enter 'c' to compare the sets\nIf not enter 'n'");
    String option = input.next();
    if("u".equalsIgnoreCase(option))
    {
        set.union(arraySetB);
    }

    if("i".equalsIgnoreCase(option))
    {
        set.intersection(arraySetA);
    }

    if("c".equalsIgnoreCase(option))
    {
        set.isEqualTo(arraySetC);
    }
    else if("n".equalsIgnoreCase(option))
    {

    }
}

This is fine
