Scala 关系运算符

Scala 关系运算符

尝试下面的示例程序，了解Scala编程语言中的所有关系运算符。

示例

object Demo {
   def main(args: Array[String]) {
      var a = 10;
      var b = 20;

      println("a == b = " + (a == b) );
      println("a != b = " + (a != b) );
      println("a > b = " + (a > b) );
      println("a < b = " + (a < b) );
      println("b >= a = " + (b >= a) );
      println("b <= a = " + (b <= a) );
   }
}

将以上程序保存在 Demo.scala 中。使用以下命令来编译和执行该程序。

命令行

>scalac Demo.scala
\>scala Demo

输出

a == b = false
a != b = true
a > b = false
a < b = true
b >= a = true
b <= a = false
