带有开头、分隔符和结尾的 Scala List addString() 方法示例
此方法与addString()方法相同，但此处还包括开始、分隔符和结束。
Method Definition: def addString(b: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the List in the String Builder and a start, a separator and an end is also included here.
示例 #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)
}
}
输出：
_1*3*5*2_
示例 #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
println(res)
}
}
输出：
(1/3/5/2)
