Scala List 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(b: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 List in the String Builder and a start, a separator and an end is also included here.

範例1：

// Scala program of addString() 
// method 
  
// 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 
  
// 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
