Scala SortedMap equals() 方法与示例
equals()方法用于检查两个 SortedMap 是否具有相同的键值对。
Method Definition: def equals(that: Any): Boolean
Return Type: It returns true if the key-value pairs of both the SortedMaps are same else it returns false.
示例 #1:
// Scala program of equals()
// method
import scala.collection.immutable.SortedMap
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating SortedMaps
val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs"-> 2)
val m2 = SortedMap("cs" -> 2, "for" -> 3, "geeks"-> 5)
// Applying equals method
val result = m1.equals(m2)
// Displays output
println(result)
}
}
输出:
true
示例 #2:
// Scala program of equals()
// method
import scala.collection.immutable.SortedMap
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating SortedMaps
val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs"-> 2)
val m2 = SortedMap("cs" -> 2, "fo" -> 2, "geeks"-> 5)
// Applying equals method
val result = m1.equals(m2)
// Displays output
println(result)
}
}
输出:
false
