「Scala」関係演算子のサンプル

書式

演算子	例	意味
>	a > b	aがbより大きいか
>=	a >= b	aがb以上か
<	a < b	aがbより小さいか
<=	a <= b	aがb以下か
==	a == b	aとbが等しいか
!=	a != b	aとbが等しくないか

使用例

object Test {
   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) );
   }
}

実行結果

$ scalac Test.scala
$ scala Test
a == b = false
a != b = true
a > b = false
a < b = true
b >= a = true
b <= a = false
