Scala中的vector向量

1.定义

val vector1 = Vector(1,2,33,"爱神的箭")
vector1.foreach(println(_))
println(vector1.getClass.getName)

输出：

 

2.Vector拼接

eg:

val vector1 = Vector(1,2,33,"爱神的箭")

val vector2 = vector1:+1
vector2.foreach(println("vector2 :",_))

val vector3 = 666+:vector1
vector3.foreach(println("vector3 :",_))

ps: 注意 拼接时候 冒号：一侧要挨着 vector元素

输出：
