Scala的Map集合练习
package gxy
import scala.collection.mutable
object Test25 {
def main(args: Array[String]): Unit = {
//可变map
val map1 = mutable.Map("123" -> "活着,余华,8888", "234" -> "朝花夕拾,鲁迅,7777", "456" -> "三体,刘慈欣,9999")
println(map1)
//1.添加
map1 += ("678" -> "某某,木苏里,6666", "789" -> "撒野,巫哲,2222")
println(map1)
val rs = map1.get("123")
println(rs.get)
println(map1("123"))
map1("123") = "活着,余华,8888"
for ((key, value) <- map1) {
println(s"$key 是 ${value}的简称")
val map2 = map1 - "123" -> "活着,余华,8888"
for ((key, value) <- map1) {
println(s"$key 是 ${value}的简称")
}
}
}
}
