val1[i] = val2[i]; // how to not make a pointer?

i'm a little confused about the different things that can happen when you use the "=" operator. it seems like in some cases it puts the value of the item on the right into the item on the left. (this is what i had come to expect.)
sometimes it seems like it makes one a pointer to the other so that they no longer act like seperate variables. what is happening and is there a way to stop that?
any references to online docs on the subject would be appreciated.
thanx.

in the case of copying arrays and array data, you can use System.arraycopy(arrayFrom,startPoint,arrayTo,startPoint,numberOfItems)
the java tutorial on sun's website is quite good for this topic: http://java.sun.com/docs/books/tutorial/java/index.html
