2. Strings

 

"Hello World"

res0: kotlin.String = Hello World

"Hello "+ "World"

res1: kotlin.String = Hello World

val my_age = 22

val my_height = 183

"I am $my_age years old, and my height is $my_height centimeters or ${my_height/100.0} meters"

res4: kotlin.String = I am 22 years old, and my height is 183 centimeters or 1.83 meters

Practice Time

1. Create three String variables for trout, haddock, and snapper.
2. Use a String template to print whether you do or don't like to eat these kinds of fish.

val trout = "trout" var haddock = "haddock" var snapper = "snapper" println("I like to eat $trout and $snapper, but not a big fan of $haddock.")

Practice Time

when statements in Kotlin are like case or switch statements in other languages.

Create a when statement with three comparisons:

• If the length of the fishName is 0, print an error message.
• If the length is in the range of 3...12, print "Good fish name".
• If it's anything else, print "OK fish name".

when(fishName.length){ 0 -> println("Fish name cannot be empty") in 3..12 -> println("Good fish name") else -> println("OK fish name") }
