An abstract computing machine, or virtual machine , JVM is a platform - independent execution environment that converts Java bytecode into machine language and executes it.
Java Virtual Machine is the one which change the source code in to the code that is executable through the system so that this helps in making the Java Platform independent as this coude is accessible in any of the operating system

jvm(java virtual machine)is the compiler of java which convert source code to byte code, which is further intepreted into machine code

JVM - Java Virtual Machine.
JVM consist of following components:-
1)Byte-code verifier :- It verify the byte-code ,it check's for unusual code.
2)Class Loader :- After verifying Class Loader will load the byte-code into the memory for execution.
3)Execution engine :-
It further consist of 2 parts :-
a)Interpreter :- It interpret the code & run.
JVM Hotspot defines when to use Interpreter or JIT.
4)Garbage Collector:- It periodically check for the object on heap , whose link is broken
So it can collect the garbage from Heap.
5) Security Manager :- It constantly monitors the code.It is 2nd level of security.[1st level is Byte-code verifier ].

java programs are compiled intoana assembly language for an imaginary machine is called java vortual machine

JVM stands for Java Virtual Machine. As the name indicates, it does not a real hardware machine but a software layer which resembles an hardware platform. JVM helps to run java programs on different Operating system platforms. The JVM will be different for different Operating Systems. ie there will be separate JVM for Windows and Linux. Now i am going to explain how Java achieves platform independents with the helps of JVM. We can write the java program on any platform. The source program is then converted to byte code using a Java compiler. The compiler will be different for different platforms. The byte code can be executed on any platform where there exist JVM.

JVM stands for Java Virtual Machine. It is the engine that drive the java code. It is the medium which converts java code to bytecode which get translated on different machine and hence it makes it platform/os independent.

JVM generates .class file that we can able to run in any OS but it should have a JVM within it.Because JVM is system dependent.

jvm stands for java virtual machine.where it converts source code into byte code but these code also not accesable by machine. where jvm play a important role. it converts Byte code to machine code.

Java is platform independant because of JVM i.e Java Virtual Machine. As different computers with different oerating system hav their own JVM,when we submit '.class' file to any ooperating system,JVM interprete the bytecode into machine level language.

JVM(java virtual machine )is java run time environment(JRE)..which converts byte code(suppose A.JAVA) in to machine languge (A.CLASS) so it can execute on any platform.
