Passing strings to method with Object as parameter?

Question

I'm having some trouble with comparing a string from my main class to another string stored in an array object in my ADT class using a method called remove. When I compare a string I enter with a string object I have stored in an array, I don't get the correct boolean return value (i.e. the two are equal - true). I thought that strings are objects by default but I'm wondering if I need to declare the string I am passing to the 'remove' method as an object?
Any suggestions?
Here is the main class and method from the ADT class (Set) I'm calling.
Thanks,
Mark

// insert a string or strings into set1

stringS1 = JOptionPane.showInputDialog(
"Enter string " + i + " of set1");
set1.insert(stringS1);
System.out.println(set1);
String stringCont1 = JOptionPane.showInputDialog("Do you wish to
continue?" +
"\n 1 for yes, 2 for no");
int cont1 = Integer.parseInt(stringCont1);
if (cont1 == 2)
break;

// remove a string from set1
for(int i = 1; i < 50; i++){
stringS1 = JOptionPane.showInputDialog(
"remove a string of set1");
System.out.println(set1.remove(stringS1));
public class Set {
private final int MAX_INDEX = 50;
private Object list[];
private int numItems = 0;

// Postcondition: set may have one less item
// success is set to true if item was removed
// Returns: true if value was removed
public boolean remove(Object item)

boolean success = false;
int index = 0;
if (numItems > MAX_INDEX) { // index out of range

while (index < numItems && !success){
     if (list[index] == item)
          success = true;
     else
          index++;
     } // end while
     if (success){  // if one was found, it is at list[index]
for (int position = index + 1; position <= numItems - 1; position++)
          list[position - 1] = list[position];
     numItems--;
} // end if
return success;
} // end remove
// output all list contents
     // Precondition : NONE
     // Postcondition: bag is unchanged
     public String toString() {
          String result = "[ ";
          for (int i = 0; i < numItems; i++)
          result = result + list[i] + " ";
          result = result + " ]";
          return result;
}

I mentioned elsewhere before I think that I have now come across Jive on other sites as well. Same bugs, holes and shit as here. Sun has certainly not proved competent, thoughtful or careful in addressing issues, rolling out new versions and other maintainence however the real fault is that Jive is terrible shit that nobody should use ever.
For example you remember all that terrible nonsense with the goatsex and the changes to profiles (and the other worse things that could have been done but weren't)? You can do that on 9 out of 10 Jive forums in the wild (in fact you can do exactly that on the 6 other Jive forums I have come across).
And some of these are big companies too. It's the worst forum software ever and I wish it wasn't written in Java.
