写一个类，利用java提供的反射机制得到用户在程序运行时输入的类名，输出该类所在继承体系中的所有类中定义的方法，所有方法需按字母排序。

比如用户输入java.util.ArrayList，输出为：

Methods of class java.util.ArrayList:

public void add(int,Object)

public boolean add(Object)

public boolean addAll(int,Collection)

public boolean addAll(Collection)

public void clear()

……

public final void wait(long,int) throws InterruptedException

class java.util.ArrayList is a subclass of class java.util.AbstractList

Methods of class java.util.AbstractList:

……

class java.util.AbstractList is a subclass of class java.util.AbstractCollection

Methods of class java.util.AbstractCollection:

……

class java.util.AbstractCollection is a subclass of class java.lang.Object

Methods of class java.lang.Object:

-To write a class, using java reflection mechanisms provided by the user program is running, enter the class name, the output of such systems where the inheritance of all classes defined in the method, all the methods basis having alphabetical order.
