When I try and use my swapCase() method. I get a memory address instead of the new instance.

How are you returning array of chars?

Just for clarification, no method should return the inner array of characters.  If you create a new array with the new results in it then you should pass that new array to a new CS2012String object and this object is what should be returned from the method. 

char[] temp = new char[some_length]

//do some stuff to put new data into temp

return new CS2012String(temp);

Double check that you also have a working toString method so you can print out your object.

Does your toString normally work for other methods?

Shouldn't this theoretically work?

Why do you need arraycopy?

You don't need to copy the array, you can get the array using "this.text[i]".

You are setting the letters uppercase, but you're not storing back into the array.

Try something like:

newUpperCase[i] = Character.toUpperCase(this.text[i]);
