Example :
示例：
List<String> list = new ArrayList<String>();
//This would give me the class name for the list reference variable.
list.getClass().getSimpleName();
I want to get the Interface name from the list reference variable. Is there any way possible to do that?
我想从列表引用变量中获取接口名称。有什么办法可以吗？

Using Reflection you can invoke the Class.getInterfaces() method which returns an Array of Interfaces that your class implements.
使用Reflection可以调用Class.getInterfaces（）方法，该方法返回类实现的接口数组。
System.out.println(list.getClass().getInterfaces()[0]);
To get just the name
得到这个名字
System.out.println(list.getClass().getInterfaces()[0].getSimpleName);

Class aClass = ... //obtain Class object.
Class[] interfaces = aClass.getInterfaces();
