Objects in Java are allocated on a system “heap” memory space. Unlike other languages, however, we needn’t manage that memory ourselves. Java takes care of memory allocation and deallocation for you. Java explicitly allocates storage for an object when you create it with the new operator. More importantly, objects are removed by garbage collection when they’re no longer referenced.
