Scala Iterator addString()用法及代码示例

此方法与addString()方法相同，但在这里我们甚至可以在Iterator的所有元素之间包括分隔符。

函数定义： def addString(b:StringBuilder, sep:String):StringBuilder
Where, sep is the separator.

返回类型：It returns the elements of an iterator in the String Builder along with the separator stated.

范例1：

// Scala program of addString() 
// method along with separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(11, 12, 13, 14) 
          
        // Applying addString method 
        // with a separator 
        val result = iter.addString(new StringBuilder(), "#") 
          
        // Displays output 
        println(result) 
      
    } 
}

输出：

11#12#13#14

范例2：

// Scala program of addString() 
// method along with separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating an Iterator  
        val iter = Iterator(5, 6, 9) 
          
        // Applying addString method 
        // with a separator 
        val result = iter.addString(new StringBuilder(), "*") 
          
        // Displays output 
        println(result) 
      
    } 
}

输出：

5*6*9
