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 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 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
