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 s1 = Stack(1, 3, 2, 7, 6, 5
          
        val s2 = Stack(1, 3, 2, 7, 6, 5)
          
        // Print the stack 
        println("Stack_1: " + s1
            
        println("Stack_2: " + s2)
            
        // Applying equals method  
        val result = s1.equals(s2
          
        // 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 s1 = Stack(1, 3, 2, 7, 6, 5
          
        val s2 = Stack(7, 3, 12, 7, 6, 5)
          
        // Print the stack 
        println("Stack_1: " + s1
            
        println("Stack_2: " + s2)
            
        // Applying equals method  
        val result = s1.equals(s2
          
        // 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
