Scala Stack equals() method with example
In Scala Stack class
, the equals() method is utilized to check if two stacks consist of the same elements in the same order.
Method Definition: def equals(o: Any): Boolean
Return Type: It returns true if both the stacks are same or else returns false.
Example #1:
// Scala program of equals() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stacks val s 1 = Stack( 1 , 3 , 2 , 7 , 6 , 5 ) val s 2 = Stack( 1 , 3 , 2 , 7 , 6 , 5 ) // Print the stack println( "Stack_1: " + s 1 ) println( "Stack_2: " + s 2 ) // Applying equals method val result = s 1 .equals(s 2 ) // Display output println( "Stack_1 == Stack_2: " + result) } } |
Output:
Stack_1: Stack(1, 3, 2, 7, 6, 5) Stack_2: Stack(1, 3, 2, 7, 6, 5) Stack_1 == Stack_2: true
Example #2:
// Scala program of equals() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stacks val s 1 = Stack( 1 , 3 , 2 , 7 , 6 , 5 ) val s 2 = Stack( 7 , 3 , 12 , 7 , 6 , 5 ) // Print the stack println( "Stack_1: " + s 1 ) println( "Stack_2: " + s 2 ) // Applying equals method val result = s 1 .equals(s 2 ) // Display output println( "Stack_1 == Stack_2: " + result) } } |
Output:
Stack_1: Stack(1, 3, 2, 7, 6, 5) Stack_2: Stack(7, 3, 12, 7, 6, 5) Stack_1 == Stack_2: false
