Understanding of stacks in Java __java

The object is placed inside the heap, and the base type data is placed on the stack.

Heap: Objects to be put out of new
Stacks: Putting basic type data and references to objects (equivalent to pointers, but the object itself is still in the heap)
Chang: public static final holds string constants and basic types of constants

Static fields: Putting static member statically defined

For right, stacks are faster than heaps.
Stack recycling mechanism: When the block ends, the basic data type is not used, it automatically destroyed

The recycle mechanism of the heap: it is automatically judged by the virtual machine

The basic type of packaging is actually the object, so put it in the heap.
New objects are created when they are run.
