Scala--基本类型和操作

webdancer posted @ 2014年1月04日 21:33 in 编程语言 with tags scala , 2129 阅读

1.类型:Scala的基本类型与Java中的Primitive type对应起来,不过都是首字母大写的类,例如Byte,Short,Int,Long,Char,Float,Double,String,Boolean

2.字面值(literal):在代码中直接写常数值的一种方式。这个Scala与Java基本相同。但是Scala提供Symbol字面值。

val s='type

3.操作:对于大部分操作符来说,与Java相同,但是“==”不同。在Scala中,"=="首先判断“==”左边是否是null,如果不是null然后条用equals方法。

4.Scala给基本类型提供了Rich Wrapper,可以有更加丰富的方法。
