Scala - 关系运算符
尝试以下示例程序来了解 Scala 编程语言中所有可用的关系运算符。
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) ); } }
将上述程序保存在 Demo.scala 中。 以下命令用于编译和执行该程序。
命令
\>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
