Tea

Report a typo

Implement the class BlackTea which is inherited from the class Tea. The class should have a public constructor with two arguments, cost and volume.

To complete the task, override the toString() method; it should return the following string pattern:

BlackTea{cost=val_cost, volume=val_volume}

where val_cost, val_volume are the values of the class parameters.

open class Tea(val cost: Int, val volume: Int) {
    override fun toString(): String {
        return "Tea{cost=$cost, volume=$volume}"
    }
}

Sample Input 1: 

2 300

Sample Output 1: 

BlackTea{cost=2, volume=300}
Write a program in Kotlin
open class Tea(val cost: Int, val volume: Int) {
override fun toString(): String {
return "cost=$cost, volume=$volume"
}
}
