Scala List addString()用法及代碼示例

此方法與addString()方法相同，但此處還包含分隔符。

函數定義： def addString(b:StringBuilder, sep:String):StringBuilder

返回類型： It returns the elements of the list to a string builder along with a separator between them.

範例1：

// Scala program of addString() 
// method with a separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a list 
        val m1 = List(1, 3, 5, 2) 
          
        // Applying addString method 
        val res = m1.addString(new StringBuilder(), "*") 
          
        // Displays output 
        println(res) 
      
    } 
}

輸出：

1*3*5*2

範例2：

// Scala program of addString() 
// method with a separator 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a list 
        val m1 = List(1, 3, 5, 2) 
          
        // Applying addString method 
        val res = m1.addString(new StringBuilder(), "_") 
          
        // Displays output 
        println(res) 
      
    } 
}

輸出：

1_3_5_2
