8. Please explain the basics of Java Garbage Collection mechanism, for instance, what does it do? What is garbage? Which memory area is the target of the Garbage Collection, etc.? BTW, is it possible that the variable \( x \) in statement "int \( x=123 \);" becomes garbage? Or is it possible that the variable \( y \) in statement "int \( y[]= \) new int[100];" becomes garbage?
