Scala部分：Scala中if条件语句的书写（包含Scala中case设置函数的使用）

package com.bjsxt.scala


object ObjectAndClass {
  def main(args: Array[String]): Unit={
    var a=190
    if(a<18){
      println("weichengnian")
    }else if(a>=18&&a<20){
      println("刚好成年")
    }else{
      println("已经成年")
    }

}

Scala中case设置函数的使用：

package com.bjsxt.scala
case class Person1(var name:String,age:Int)
object Lesson_Class {
  def main(args:Array[String]):Unit={
    val p1=Person1("zhangsan",18)
    println(p1.name)
    val p2=new Person1("zhangsan",18)
    println(p1==p2)
  }
}

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

package com.bjsxt.scala
case class Person1(var name:String,age:Int)
object Lesson_Class {
  def main(args:Array[String]):Unit={
    val p1=Person1("zhangsan",18)
    println(p1.name)
    val p2=new Person1("zhangsan",18)
    println(p1==p2)
  }
}
