Скачать или смотреть what is the javap tool and how it works...!

The javap tool is a command-line utility provided by the Java Development Kit (JDK) that is used to disassemble Java bytecode. It stands for "Java Disassembler" and is part of the JDK package.

When you compile a Java source file (.java), the Java compiler (javac) converts it into bytecode (.class files). This bytecode is then executed by the Java Virtual Machine (JVM). The javap tool allows you to examine the bytecode instructions generated by the compiler for a given class file.

Using javap, you can analyze the structure of classes, interfaces, and other Java types. It provides information about the members (fields and methods) of a class, their access modifiers, return types, parameter types, and more. This tool is particularly useful for understanding the low-level details of Java code and for debugging and optimizing Java applications.
