I am rather sure that this is impossible, but I think I might as well try. I have some existing code which I do not own, and I want to keep my code completely seperate, say this was the original class

public class myClass
{
    public static void doStuffs()
        {
             x = x + 1;
        }
}

and the other class had:

public static void setData()
       {
             //Set the data
       }

Is it possible to call doStuffs() when setData() is called without modifying the the actual setData() method? If so how?

可以通过字节码检测： ByteCodeInstrumentation

有几个库可以提供帮助，例如ASM、Javassist等

是的，可以使用Javaassist。
您可以使用此库在运行时修改字节码
