What is JVM?
JVM means Java Virtual Machine, It provides a complete Runtime Environment to Execute Java Byte Code.
JVM is the part of JRE means when we install JRE in the machine then JVM Environment will be created by default.
JVM Component:-
ASSIGNMENTS on Java:-
JVM is the part of JRE means when we install JRE in the machine then JVM Environment will be created by default.
JVM Component:-
JVM Architecture?
JVM means Java Virtual Machine, It will divide the complete runtime environment into four different parts.
1) ClassLoader SubSystem:-
1.1) Loading ---> When we execute the program the loader will load the class files using Bootstrap, extension, and application loader.
1.2) Linking ----> It is used to link all libraries of byte code that will be used into the java program
1.3) Initialization---> after successfully loading and linking, the byte code file will be initialized into memory.
2) Memory Area
2.1) Stack Memory:-
It is used to store the data for value type data type
for example, int, char, float, boolean, and all primitive data type elements store data under stack memory.
2.2) Heap Memory:-
It is used to store the data for reference type of data type such as Object, String, String Buffer etc
2.3) Method Area:-
It is used to contain the data of Methods of class.
2.4) PC Register:-
It is used to solve the expression of any mathematical, logical, and conditional expression in the program.
2.5) Native Method Stack:-
It is used to contain the references of c and c++ languages and store them.
3) Execution Engine
3.1) Interpretar:- It is used to read the byte code line by line and process it's output.
3.2) JIT:- It is used to convert byte code to machine code.it means Just-In-Time Compiler.
3.3) GC:- It means Garbage Collector, it is used to provide automatic memory management.
4) Native Method Library
4.1) JNI (Java Native Interface):- It is used to execute other programming code(c and c++) and convert it into machine code.
4.2) Native Method Library:- It is used to contain the library of C and C++ languages and integrate it into java byte code.
