Compiler!!!!!! You guys already know compiler converts codes into machine code which can be understood by the computer. But did you ever think about getting the code from machine code? If your answer is no or you didn’t know yet about this then this article is for you. In this article, I am going to tell you about how can you get the structure of your code from the bytecode. This article is too short and sweet, so it's not going to take your too much time xD.
Many people say that you can’t get the code from byte code, and some people say that you can get the code from byte code. Are they both true? or wrong? Let me tell you, you can not get each line of your code but you can get the structure of the code. So, it will help you to debug in very big projects, and that is why I am going to cover this topic today. Let's start with an example in Java.
Here is our small java file in which there are three class members: constructor, variable and method. Now when you compile the java file then it will create a .class file.
If you want to get the structure of that class from byte code then you have to write “javap filename”. In my case, I made java file named nothing so I will type javap nothing and then it will give me something like this......
So, you can see it is giving me the structure. Public class, variable mike, nothing constructor and show method. We can also get the structure of pre-defined classes. Example: java.lang.Object
So, here you can see the structure of java.lang.Object class. By this command, you can get the structure of any class you want.
