Scala Mutable SortedMap 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。

Method Definition: def addString(b:StringBuilder, sep:String):StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the SortedMap in the String Builder and a separator is also added between the elements of the SortedMap.

範例1：


// Scala program of addString()
// method with a separator
import scala.collection.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 2)
          
        // Applying addString method
        // and a separator
        val result = m1.addString(new StringBuilder(), "_") 
          
        // Displays output
        println(result)
      
    }
}

輸出：

cs -> 2_for -> 3_geeks -> 5

範例2：


// Scala program of addString()
// method with a separator
import scala.collection.SortedMap
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "geeks" -> 2)
          
        // Applying addString method
        // and a separator
        val result = m1.addString(new StringBuilder(), "_") 
          
        // Displays output
        println(result)
          
    }
}

輸出：

for -> 3_geeks -> 2

因此，這裏刪除了相同的鍵。
