Scala Set equals() 方法与示例

equals()方法用于检查两个集合是否具有相同的元素。

Method Definition: def equals(that: Any): Boolean

Return Type: It returns true if the elements of both the sets 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 sets 
        val s1 = Set("geeks", "for", "cs") 
        val s2 = Set("cs", "for", "geeks") 
          
        // Applying equals method 
        val result = s1.equals(s2) 
          
        // 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 sets 
        val s1 = Set(11, 10, 2019) 
        val s2 = Set(9, 10, 2018) 
          
        // Applying equals method 
        val result = s1.equals(s2) 
          
        // Displays output 
        println(result) 
      
    } 
} 

输出：

false
