Example #1:
// Scala program of subsetOf() // method // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a set val s 1 = Set( 4 , 12 , 2 , 31 ) val s 2 = Set( 4 , 12 ) // Applying subsetOf method val result = s 2 .subsetOf(s 1 ) // 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 s 1 = Set( 4 , 12 , 2 , 31 ) val s 2 = Set( 4 , 12 ) // Applying subsetOf method val result = s 1 .subsetOf(s 2 ) // Display output println(result) } } |
Output:
false
