可是还要循环//方法2Function<Record, Map> recordToMap = record -> {returnrecord.asMap();};for(Record record : records) {System.out.println("recordToMap.apply(record):"+ recordToMap.apply(record));}和方法1没有什么区别

在java.util.function包下,定义了大量的函数式接口,每个接口都有且只有一个抽象方法,这些接口的区别在于其中的抽象方法的参数和返回值不同。 Lambda 表达式 One issue with anonymous classes is that if the implementation of your anonymous class is very simple, such as an interface that contains only one ...
