带有分隔符的 Scala Iterator addString() 方法和示例

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

Method Definition : def addString(b: StringBuilder, sep: String): StringBuilder
Where, sep is the separator.

Return Type :It returns the elements of an iterator in the String Builder along with the separator stated.

示例 #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

示例 #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
