    val cash = 95
    var percentage = 10.34


    var language: String      //  String Variable Declaration
    language = "english"       // Initializing the variaable

    val score: Int          // Int variable Declaration
    score = 200             // Initializing the variaable


                /* ............... END ............... */




  • In Kotlin either var or val keyword is used to declare the variable.
  • We don't want to specify the type of variable, Kotlin implicitly conveting to the proper data types.
  • val in Kotlin : The variable declared using val keyword cannot be changed once the value is assigned.
  • It is similar to final variable in Java.
  • var in Kotlin - The variable declared using var keyword can be changed later in the program. It corresponds to regular Java variable.
  • Go through the above program to get more understanding about Kotlin var and val.
