Identify a key that is well-chosen so that it is "hard to guess." In general, the following factors should be considered when choosing the key:
1. The key must be available to all code that uses it. This may require modifying the public interface of some object.
2. The key must be secret, meaning that the key should not be known outside the compiler implementation. An implementation could use a fixed key or a key derived from a particular application.
3. The key should be stable so that it can be reused. If the key is secret, an implementation should generally reuse a key across different applications.
Binary format:
The Java Virtual Machine specifications and class files are written in the binary format. This binary format is machine-independent, which means that a binary of this format can be processed by a Java virtual machine on any system that supports the Java platform.
This binary format allows a Java virtual machine to be implemented as a standalone component, such as a Java virtual machine or interpreter, or to be embedded in a host environment, such as a general-purpose operating system. (See the section on Java virtual machine specifications below for more information.)
Overview:
In most cases, the key used to generate the binary representation of Java source code is stored in the header of the binary representation of a Java class file. Class files use a mechanism known as the constant pool to store information about the classes, fields, methods, and so forth that make up the class. The constant pool is a table that contains the information necessary to find the classes, fields, and methods used by the classes defined in the class file.
The constant pool is defined as a sequence of constant pool entries. Each entry is a 32-bit entry. (The term constant pool is used throughout this specification to refer to the constant pool sequence.)
The key that is used to generate the constant pool entries is embedded into the binary representation of a class file. The key is typically the same as the key used to generate the binary representation of the class file. However, because it is conceivable that two class files might have the same binary representation, the key embedded in the class file header is typically different from the key used to generate the binary representation of the class file. (It is not necessary that the key be different for these two purposes, but it is convenient to have a fixed key for both purposes.)
The constant pool consists of a sequence of entries. Each entry is a constant pool entry.
