+import java.util.function.Supplier;
+
+/*
+    JDK为了避免各个程序原定义一些重复的无效的函数式接口，所以，它就提供了一些常用的函数式接口
+    Supplier<T>  ：表示生产者
+    T:泛型，用来决定生产者要生产数据类型
+
+    Supplier<T> 提供了一个生产方法:T get() 获得结果。
+
+    总结：Supplier<T>的作用，当我们想要定义一个无参有返回值的函数式接口时，就使用Supplier
+
+    举例：想要定义一个无参有返回值(String)的函数式接口:Supplier<String> -->String get()
+    举例：想要定义一个无参有返回值(Student)的函数式接口:Supplier<Student> -->Student get()
