insertItem method

I am having issues with the following code:

Code Java:

---

    @Override
    public void insertItem(Comparable item, int position) {
        //throw new UnsupportedOperationException("Not supported yet.");
        if (!(this.full())){
            throw new SimpleListException("Full list");
        }
        else{
                for(int i = 0; i < freeListArray.length; i++){ //find first free location
                    if(freeListArray[i] != NULL){
			break;
                    }
                }
		linksArray[i] = freeListArray[i]; //put location in links
		dataArray[linksArray[i]] = item;  //put item into data
		temp = linksArray[i];
		linksArray[dataArray[temp]] = -1; //show where end of array is        
            }
    }
 
Constructor is as follows:
 
    public SimpleComparableList(){
        this.capacity = DEFAULT_CAPACITY;
        this.currentPosition = 1;
        this.dataArray = new String[capacity];
        this.linksArray = new int[capacity];
        this.freeListArray = new int[capacity];
    }
 
    public SimpleComparableList(int capacity){       
    // Constructs and initializes a list that is empty. Current list size is 
    // zero and current position is set to one.        
        this.capacity = capacity;                 
        this.currentPosition = 1; 
        this.dataArray = new String[capacity];
        this.linksArray = new int[capacity];
        this.freeListArray = new int[capacity];        
    }

Can someone please fix my code and explain what was wrong with it?

Thank you!

You need to explain a bit more about what is wrong...since there is no SSCCE we can't run the code and test how it misbehaves. Do you get exceptions? Does it compile? Does it misbehave? You need to be as precise as possible

It compiles with errors. It does not misbehave. It runs a Test GUI consisting of:

Default Constructor OK
Constructor with given max size OK
iterator()
insertItem(Comparable item)
insertItem(Comparable item, int position)
removeItem()
removeItem(int position)

Please post the full text of the error messages. Java error messages usually tell you what's wrong and where.

I suspect that when you do finally get it to compile, throwing a SimpleListException if the list is not full will make it hard to insert anything:

Code :

---

if (!(this.full())){
   throw new SimpleListException("Full list");
}

---

WTF?

@dlorde
I think this OP submits his sub program to an online black box that compiles it and executes it and returns some report.
But he refuses to tell us about it.

Yeah, looks like it. There does seem to be a rash of posts at present from people who won't listen or answer or follow links, or who keep changing their minds about what their problem is...

This one made me laugh!
