Conclusion

11. Conclusion Great job on completing this introduction to Kotlin! You worked with simple programs in Kotlin and ran them to see text printed to the output. You modified the programs in different ways and observed how those changes affected the output. It's normal to make mistakes when programming, so you also began to learn about how to troubleshoot and correct errors in your code, which is an important skill that will help you in the future. Move on to the next codelab to learn how to use variables in Kotlin so that you can create more interesting programs! Summary A Kotlin program requires a main function as the entry point of the program. To define a function in Kotlin, use the  fun  keyword, followed by the name of the function, any inputs enclosed in parentheses, followed by the function body enclosed in curly braces. The name of a function should follow camel case convention and start with a lowercase letter. Use the  println()  function call to print some te...

Exercises

Can you read the code in this program and guess what the output is (without running it in Kotlin Playground)? fun main () {     println ( "1" )     println ( "2" )     println ( "3" ) } Once you have a guess, copy and paste this code into the Kotlin Playground to check your answer. Use the Kotlin Playground to create a program that outputs the following messages: Copy and paste this program into the Kotlin Playground. fun main{ (I'm learning Kotlin!WALLALL Knowledge Base) {     println ( "WALLALL" )     println ( "WALLALL Knowledge Base" )     println("WALLALL " )     println ( "WALLALL" )     println ( "WALLALL Knowledge Base" ) } Fix the program so that it prints this output: WALLALL WALLALL Knowledge Base WALLALL WALLALL WALLALL Knowledge Base For some early practice on troubleshooting, fix the errors in the following exercises. For each exercise, copy the code into the Kotlin Playground in your br...
