Scala Mutable SortedSet forall() method
  • Last Updated : 26 Mar, 2020

In Scala mutable collections, SortedSet forall() method is utilized to check if the given predicate satisfies all the elements of the SortedSet or not.

Method Definition: def forall(p: (A) => Boolean): Boolean

Return Type: It returns true if the stated predicate holds true for all the elements of the SortedSet else it returns false.

Example #1:




// Scala program of forall() 
// method 
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
        // Creating a SortedSet 
        val s1 = SortedSet(13, 7, 12, 9, 21
          
        // Applying forall method 
        val result = s1.forall(y => {y % 3 == 0}) 
          
        // Displays output 
        println(result) 
      
    
Output:
false

Example #2:




// Scala program of forall() 
// method 
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
        // Creating a SortedSet 
        val s1 = SortedSet(15, 12, 21, 30
          
        // Applying forall method 
        val result = s1.forall(y => {y % 3 == 0}) 
          
        // Displays output 
        println(result) 
      
    
Output:
true
