带有分隔符的 Scala List addString() 方法和示例

此方法与addString()方法相同，但此处还包括一个分隔符。

Method Definition: def addString(b: StringBuilder, sep: String): StringBuilder

Return Type: It returns the elements of the list to a string builder along with a separator between them.

示例 #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)
      
    }
}

输出：

1*3*5*2

示例 #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)
      
    }
}

输出：

1_3_5_2
