Scala Map addString()用法及代碼示例

該方法與addString()方法相同，但是這裏也包括開始，分隔符和結束。

函數定義： def addString(sb:mutable.StringBuilder, start:String, sep:String, end:String):mutable.StringBuilder

Where, sep is the separator stated.

返回類型： It returns the elements of the map in the String Builder and a start, a separator and an end is also included here.

範例1：

// Scala program of addString() method 
// with a start, a separator and an 
// end 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating map 
        val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 3) 
          
        // Applying addString method  
        val result = m1.addString(new StringBuilder(), ">>>", "|", "--") 
          
        // Displays output 
        println(result) 
    } 
}

輸出：

>>>geeks -> 5|for -> 3|cs -> 3--

範例2：

// Scala program of addString() method 
// with a start, a separator and an 
// end 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating map 
        val m1 = Map("geeks" -> 5, "for" -> 3, "for" -> 3) 
          
        // Applying addString method  
        val result = m1.addString(new StringBuilder(), ">>>", "|", "--") 
          
        // Displays output 
        println(result) 
    } 
}

輸出：

>>>geeks -> 5|for -> 3--

因此，此處刪除了相同的鍵。
