是将一个基本数据类型的double值转换为对应的包装类Double对象。在Java中,基本数据类型和对应的包装类是有关联的,可以通过包装类来操作基本数据类型。 Double是Java中的一个包装类,...
For example: Computer::getAge;Copy We’re looking at a method reference to the methodgetAgedefined in theComputerclass. We can then operate with that function: Function<Computer, Integer> getAge = Computer::getAge;IntegercomputerAge=getAge.apply(c1);Copy ...
