In our example we can see the string for os.name is loaded with key #33:

All the values are referenced by a unique key. This map basically consists of literal values, strings and other references to types or fields.

Constant Pool: The JVM loads a hash-map of constants for each type that it sees in the classpath.

General Information: This section shows specific info about the JVM version that compiled this class, the number of constants in the constant pool, access flags for this class, and some other counters:.

In the panel that appears on the right hand side we can see some information about the Bytecode.

Click on View -> Show Bytecode with Jclasslib.

Then, depending on this cases, it prints some strings.

The above code just retrieves the os.name system property and checks if it contains the string linux.

The Bytecode itself is a format that follows a specification from the Java Virtual Machine Specification. java files to the generic bytecode format. The javac on the other-hand will compile your.

In other words, when you install Java on your Windows PC, the java tool will use a platform specific runtime and a JIT compiler to run your code on Windows. class files from linux to windows and run them there without issues and vice versa. That means that the code compiled in a Linux machine and the code compiled in a Windows machine should work in the JVM either ways. The advantages of this approach is mainly cross-platform compatibility, as the compiled code, which is called bytecode, is supposed to be platform agnostic. The JVM in simple words is an engine that reads compiled code in a format that is specified from a Java Virtual Machine Specification and executes it on the current machine.

In this tutorial, we are going to see a 10000 foot view of the JVM, understand some basic concepts and learn how to read Bytecode from a simple program. Even at the basic level, we should be able to understand and explain with simple words what is the JVM, how the compilation works, what is Bytecode, and how to read it. When working with the JVM ecosystem, it's important to spend some time and understand what is happening behind the scenes.
