大家帮忙看看这个面试题！
public class Test{

public static void Temp(String ClassName,String MethodName,String args)

{

.................................................

}

public static void main(String args[])

{

Temp("Hello","Demo","nihao");

}

}

class Hello

{

public void Demo(String args)

{

System.out.println("Hello"+args);

}

}

写一个方法：public void Temp(String ClassName,String MethodName,String args)，使得这个方法能够实现调用，其中ClassName为类名，MethodName为方法名，args参数。例如：Temp("Hello","Demo","nihao");
