You can’t Use a variable before Initialization. You can’t Delete a variable. If you want to analyse byte code I suggest using ObjectWeb’s ASM library. 2 solved Java tool to perform a specific “Data Analysis” on ASM code [closed]

We see runtime performance issues compiling Java 6 bytecode with Java 7. Is that expected? No. It is not expected. It is possible … but I wouldn’t have predicted it, and I can’t think of an obvious explanation. What are the downsides/benefits of doing that? I can think of no real benefits to your problem … Read more
You can use some obfuscation tools, like ProGuard. A self written ClassLoader, must be placed in a standard .class file, that the JVM can load it. And then you secure loader can be reverse engineered. Don’t do it by yourself. Writing “secure” code without knowing cryptographic algorithms will lead to error-prone an insecure code 5 … Read more
There are no tools that I am aware of that do this, and a JVM will not just blindly load all classes contained on its class path on boot. It just loads whatever you told it is the main class, and whenever it loads a class, it checks which other classes it needs to load … Read more
