Since you didn't really specify what you are looking for, take a look at these System Properties:

"java.vm.name"
"java.home"
"java.version"
"java.vendor"
"java.specification.vendor"

Like this:

System.out.println(System.getProperty("java.vm.name"));
System.out.println(System.getProperty("java.home"));
System.out.println(System.getProperty("java.vendor"));
System.out.println(System.getProperty("java.version"));
System.out.println(System.getProperty("java.specification.vendor"));

it is ManagementFactory.getRuntimeMXBean().getName() – Shamim Ahmmed Oct 03 '13 at 17:25 — Shamim Ahmmed, Oct 03 '13 at 17:25

There are two kind of JVM names namely:

Java Virtual Machine implementation name : Java HotSpot(TM) Client VM
Java Virtual Machine specification vendor : Oracle Corporation

Type code in java program and see output:-

 System.out.println("Java Virtual Machine specification version  : "+System.getProperty("java.vm.specification.version")); 
 System.out.println("Java Virtual Machine specification vendor : "+System.getProperty("java.vm.specification.vendor"));
 System.out.println("Java Virtual Machine specification name : "+System.getProperty("java.vm.specification.name"));
 System.out.println("Java Virtual Machine implementation version : "+System.getProperty("java.vm.version"));
 System.out.println("Java Virtual Machine implementation vendor : "+System.getProperty("java.vm.vendor"));
 System.out.println("Java Virtual Machine implementation name : "+System.getProperty("java.vm.name"));

refer https://docs.oracle.com/cd/E15289_01/doc.40/e15062/sysprop.htm

see output of java -version

To know ur JVM vendor: type java -version in cmd and see third line of it.

eg:

C:\Users\jack>java -version

java version "1.8.0_74"

Java(TM) SE Runtime Environment (build 1.8.0_74-b02)

Java HotSpot(TM) Client VM (build 25.74-b02, mixed mode)

If you are trying to get the process id of the current process you can do this.

How can a Java program get its own process ID?

There is a variety of properties you can get with System.getProperty(), java.vm.name seems like what you need.

System.getProperty("java.version") should do the trick
