一些简单的scala语句：

package cn.sendohhadoop.scala/** * Created by sendoh on 2015/2/2. */class Basic {}object Basic {  def hello(name : String = "lllf") : String = {    "Hello :" + name  }  def helloscala(){    println("Hello scala !")  }  val add = (x : Int, y : Int) => x + y  def add1(x : Int)(y : Int) = x + y  def printEveryChar(c : String*) = {    c.foreach(x => println(x))  }  def main(args : Array[String]): Unit ={    //println("Hello scala")    //println(hello("Scala"))    //helloscala()    //println(add(2,3))    //println(add1(3)(5))    //printEveryChar("s","c","a","l","a")    //val x = 1    //val a = if(x > 0) 1 else 0    //println(a)    //var (n, r) = (10, 0)    //while(n > 0){    //  r = r + n    //  n = n - 1    //}    //println(r)    //foreach    //for(i <- 1 to 10){//a.b("xxx") = a b "xxx"  to 9 = until 10    //  println(i)   //}    for(i <- 1 to 10 if i % 2 == 0){      println(i)    }  }}
