# Scala Set dropWhile() method with example

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()
```
