简单测试Scala跑程序

应用场景

当本地部署搭建完Scala开发环境后，那么就可以利用IDE开发工具进行Scala语言编程，编写一些工具等等，这里写一些简单的语法涉及，来熟悉下Scala。

运行代码

package epoint.com.cn.test001object test001 { def main(args: Array[String]) { val msg = "hello world" val greetStrings = Array("i", "like", "scala") println(msg) println(max(5, 6)) greet() printargs(greetStrings)val oneTwo = List(1, 2) val threeFour = List(3, 4) val oneTwoThreeFour = oneTwo ::: threeFour println(oneTwo + " and " + threeFour + " were not mutated.") println("Thus, " + oneTwoThreeFour + " is a new list")val pair = (99, "Luftballons") println(pair._1) println(pair._2)var jetSet = Set("Boeing", "Airbus") jetSet += "Lear" println(jetSet.contains("Boeing"))val romanNumeral = Map(1 -> "I", 2 -> "II", 3 -> "III", 4 -> "IV", 5 -> "V") println(romanNumeral(4))}def max(x: Int, y: Int): Int = { if (x > y) x else y }def greet() = println("xubin nihao")def printargs(args: Array[String]) { var i = 0 while (i < args.length) { println(args(i)) i += 1 } }}

输出打印：
