The following editor will bring you an article that discusses the Java heap area, method area and stack area in detail. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look.
Heap area:Only stores classobjects, shared by threads;
Method area: Also called static storage area, which stores class files and static data, shared by threads;
Stack area: Storage method local variables, basic type variable area, execution environment context, operation instruction area, threads are not shared;
class A { private String a = “aa”; //a在堆区 public boolean methodB() { String b = “bb”; //b在栈区 final String c = “cc”; // c在栈区 } }
The above is the detailed content of Briefly introduce the code examples of heap area, method area and stack area in Java. For more information, please follow other related articles on the PHP Chinese website!
