In the structure of the previous OPENJDK source research Note (vii) –java code file (. Class), we have a general idea of the structure of the Java bytecode file. This article describes in detail how to read most of the details of a. class file. 1. Construct the file Byte code file user.class String userclass = "C:/user.class"; File File = new file (userclass); 2. Construct the input streamFileInputStream fin = new FileInputStream (file); DataI
