Describe the four-step Java byte code verification process.

What will be an ideal response?


The four-pass verification process is composed of the following steps:
1 Check magic number. The first four bytes of the file are 0xCAFEBABE.
2 Syntax checking. Performs syntax verification without code inspection. For example, checking for a nonobject superclass.
3 Machine instruction checking. Parsing all byte codes to ensure the opcodes are valid, method arguments are of proper type, and opcode arguments are appropriate.
4 Access-control modifier checking. This verification is done when a method is invoked.
