你好。
我需要有人向我解释,这个段的意思:

Think carefully about how many objects are on the heap after a code

statement or block executes. The exam will expect you to know, for example, that the

preceding code produces just one object (the array assigned to the reference variable

named threads). The single object referenced by threads holds five Thread reference

variables, but no Thread objects have been created or assigned to those references.
