Scala Map equals() 方法与示例

equals()方法用于检查两个映射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 maps are same else it returns false.

示例 #1：

// Scala program of equals()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating maps
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs"-> 2)
        val m2 = Map("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
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating maps
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs"-> 2)
        val m2 = Map("cs" -> 2, "fo" -> 2, "geeks"-> 5)
          
        // Applying equals method
        val result = m1.equals(m2)
          
        // Displays output
        println(result)
      
    }
}

输出：

false
