Question - Is there any difference between == operator and === operator?
Answer -
Yes. The == operator is used to compare the values stored in variables and the === operator is used to check if the reference of the variables are equal or not. But in the case of primitive types, the === operator also checks for the value and not reference.
// primitive example
val int1 = 10
val int2 = 10
println(int1 == int2) // true
println(int1 === int2) // true
// wrapper example
val num1 = Integer(10)
val num2 = Integer(10)
println(num1 == num2) // true
println(num1 === num2) //false
