The answer to 'unloading classes in java' says -
"The only way that a Class can be unloaded is if the Classloader used is garbage collected." I took a look at the JLS but couldn't understand it
Why is this the case?
回答1:
A class is only unloaded when it is garbage collected, and for that to happen there must be no references to it anywhere. And the classloader keeps a reference to each class it loads.
