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
