Scala Set subsetOf() method with example

The subsetOf() method is utilized to test if a set is a subset of another set.

Method Definition: def subsetOf(that: Set[A]): Boolean Return Type: It returns true if a set is subset of another set else it returns false.

Example #1:

Scala

// Scala program of subsetOf() 
// method 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a set 
        val s1 = Set(4, 12, 2, 31) 
        
        val s2 = Set(4, 12)
        
        // Applying subsetOf method 
        val result = s2.subsetOf(s1)
        
        // Display output
        println(result)
    } 
}

Output:

true

Example #2:

Scala

// Scala program of subsetOf() 
// method 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a set 
        val s1 = Set(4, 12, 2, 31) 
        
        val s2 = Set(4, 12)
        
        // Applying subsetOf method 
        val result = s1.subsetOf(s2)
        
        // Display output
        println(result)
    } 
}

Output:

false
