Scala Map equals()用法及代碼示例


equals()方法用於檢查兩個映射是否具有相同的key-values對。

函數定義: def equals(that: Any): Boolean

返回類型: It returns true if the key-value pairs of both the maps are same else it returns false.



範例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) 
      
    } 
}
輸出:
true

範例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)
