Android Kotlin Digest #2
Back again with Kotlin I learnt. Kotlin runs on Java Virtual Machine (JVM). Syntax for declaring variables: Mutable: var name: Type = value Immutable: val name: Type = value Type Bit width Double 64 Float 32 Long 64 Int 32 Short 16 Byte 8 Kotlin 1.1 supports underscores ( _ ) in numeric values for readability: val mySalary = 1_000_000 val myCreditCardBill = 20_000 Difference between == and === : val a : Int = 10 val b : Int = 10 (a == b) // gives true (a === b) // gives true Note: Here primitive types are compared. When the primitive types are nullable it is turned into references and following is the result: val a : Int? = 10 val b : Int? = 10 (a == b) // gives true (a === b) // gives false Note: Here a and b becomes references and hence comparision with === results false. Type converters: 'c'.toInt() 80.toString() A raw string is delimited by a triple quote ( """ ), contains no escaping a...
