Scala Iterator filterNot()用法及代码示例


filterNot()方法属于AbstractIterator类的具体值成员。它在类Iterator和IterableOnceOps中定义。它选择指定迭代器中不满足给定谓词的所有元素。

函数定义: def filterNot(p:(A) => Boolean):Iterator[A]

返回类型: It returns a new iterator containing all the elements of the stated iterator that do not satisfies the given predicate p.



范例1:

// Scala program of filterNot() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(3, 9, 5, 1, 13) 
          
        // Applying filterNot method 
        val x = iter.filterNot(x => {x % 3 != 0}) 
          
        // Applying next method 
        val result = x.next() 
          
        // Displays output 
        println(result) 
      
    } 
}
输出:
3

范例2:

// Scala program of filterNot() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(2, 4, 5, 1, 13) 
          
        // Applying filterNot method 
        val x = iter.filterNot(x => {x % 2 == 0}) 
          
        // Applying next method 
        val result = x.next() 
          
        // Displays output 
        println(result) 
      
    } 
}
输出:
5
