next()方法屬於類AbstractIterator的Abstract Value Members。它在類Iterator中定義。它給出了所述迭代器的下一個元素,並推進了迭代器。
函數定義: def next():A
返回類型:It returns the next element of the stated collection.
範例1:
// Scala program of next()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating an Iterator
val iter = Iterator(5, 8, 10, 13, 15)
// Applying next method
val result = iter.next
// Applying next method
// again
val res = iter.next
// Displays output
println(result)
println(res)
}
}
輸出:
5 8
範例2:
// Scala program of next()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating an Iterator
val iter = Iterator(1.1, 2.2)
// Applying next method
val result = iter.next
// Applying next method
// again
val res = iter.next
// Displays output
println(result)
println(res)
}
}
輸出:
1.1 2.2
