Scala Mutable SortedMap equals()用法及代碼示例


該方法equals()被用來檢查兩個SortedMaps是否具有相同key-values對或不是。

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.

範例1:

// Scala program of equals() 
// method 
import scala.collection.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) 
      
    } 
}
輸出:
true

範例2:

// Scala program of equals() 
// method 
import scala.collection.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)
