Java Memory analysis

In Java, memory management is divided into: stack (stack), heap, datasegment (data segment), Codesegment (code snippet)

Stack: base data type (Byte,short,int,long,char,float,double,boolean), local variable, object's reference address

Heap: Store object instances, new comes out of the place.
Datasegment (data segment): Static variables and string constants

Codesegment (Code snippet): Store code as the name implies

Instance:

Here's an example of how a Java variable is stored in memory.

Code Segment:arraylistlist[]=new arraylist[2];

arraylist[0]=2;arraylist[1]=3;arraylist[2]=4;

Because list[] is a variable, this is a declaration we put into the stack.

The variables that are instantiated from each subsequent array are then placed in the heap.

The value of a real variable is constant, so it is placed in a constant pool, which is the datasegment.
