I. In c, there are several storage areas1. Stack-automatically allocated and released by the compiler2. Heap-generally released by the programmer. If the programmer does not release the heap, it may be recycled by the OS at the end of the program.3.

Java memory allocation: 1. Register: we cannot control it in the program2. STACK: stores basic data and object references, but the object itself is not stored in the stack, but stored in the heap.3. Heap: store data generated with new4. static
