The dropWhile() method is utilized to drop the longest prefix of elements from the set that satisfies the stated condition.
Method Definition: def dropWhile(p: (A) => Boolean): Set[A]
Return Type: It returns a set containing all the elements after dropping the longest prefix of elements from the set that satisfies the stated condition.
Example #1:
// Scala program of dropWhile() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a list
var s 1 = Set( 1 , 3 , 5 , 4 , 2 )
// Print the set
println(s 1 )
// Applying dropWhile method
var res = s 1 .dropWhile(x => {x % 2 ! = 0 })
// Displays output
println(res)
}
} |
Output:
Set(5, 1, 2, 3, 4) Set(2, 3, 4)
Example #2:
// Scala program of dropWhile() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a list
var s 1 = Set( 1 , 3 , 5 , 4 , 2 )
// Print the set
println(s 1 )
// Applying dropWhile method
var res = s 1 .dropWhile(x => true )
// Displays output
println(res)
}
} |
Output:
Set(5, 1, 2, 3, 4) Set()
