diff()方法用於計算一組和另一組的差。
函數定義: def diff(that: Set[A]): Set[A]
返回類型: It returns a set which is the difference between two sets.
範例1:
// Scala program of diff()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating sets
val s1 = Set(1, 2, 3, 4, 5)
val s2 = Set(1, 2, 3)
// Applying diff method
val s3 = s1.diff(s2)
// Displays output
for(elem <- s3)
println(elem)
}
}
輸出:
5 4
範例2:
// Scala program of diff()
// method
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating sets
val s1 = Set(1, 2, 3, 4, 5)
val s2 = Set(6, 2, 7, 8)
// Applying diff method
val s3 = s1.diff(s2)
// Displays output
for(elem <- s3)
println(elem)
}
}
輸出:
5 1 3 4
