Question

I am using Scala to do some work with Java s reflection API. But I can t seem to figure out how to access in Scala what in Java would be: int.class, float.class, boolean.class.

基本上来说,是原始数据类型。

因此,斜体的构造是什么?

Answer 1

不存在。相应的盒式型号各有一个静态领域,称为TYPE,代表了原始类型。你们指的是什么?

e. 例如,用于t/Integer:

http://docs.oracle.com/javase/6/docs/api/java/lang/Integer.html#TYPE

If so, you reference it from Scala just like you would in Java:

scala> Integer.TYPE
res0: java.lang.Class[java.lang.Integer] = int

Answer 2

Welcome to Scala version 2.10.0-20120430-094203-cfd037271e (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_25).
Type in expressions to have them evaluated.
Type :help for more information.

scala> classOf[Int]
res0: Class[Int] = int

scala> classOf[Integer]
res1: Class[Integer] = class java.lang.Integer
