Obfuscate java program source code
Turn:
class HelloWorld{
public static void main(String[] args){
System.out.println("Hello World");
int loop = 3;
for(int i = 0; i < loop; i++){
System.out.println(i);
}
}
}Into:

Q Does this compile?
A It does. The Java compiler decodes the unicode first and it becomes a vaild program again.
Q Why would I want to do this?
A You don't.
Q Are there any advantages to doing this?
A No, unless your goal is to create unreadable code.
Q Why don't you convert all the characters in the program?
A I like it being a mix of both. It keeps the program structure, but still makes it impossible to read.
