Supposedly, and they are, short lived objects and I have read that the garbage collector should re-claim them quickly. However I'm still worried about it. How does the GC know that I'm throwing it away quickly? So confusing.

It doesn't know it. It assumes it. This is called the generational hypothesis on which all generational garbage collectors are built:

• almost all objects die young
• almost no old objects contain references to new objects

Objects which satisfy this hypothesis are very cheap (even cheaper, in fact, than malloc and free in languages like C), only objects which violate one or both assumptions are expensive.
