The resulting object is called an object copy or simply copy of the original object. Copying is basic but has subtleties and can have significant overhead. There are several ways to copy an object, most commonly by a copy constructor or cloning. Copying is done mostly so the copy can be modified or moved, or the current value preserved.

It is an improvement on the previous stop-and-copy technique. [citation needed] Cheney's algorithm reclaims items as follows: Object references on the stack. Object references on the stack are checked. One of the two following actions is taken for each object reference that points to an object in from-space:
==References== {{reflist}} Note: This is by far the most popular system for inline citations, but sometimes you will find other styles being used in an article. This is acceptable, and you shouldn't change it or mix styles. To add a new reference, just copy and modify an existing one.
