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...

The corresponding cell of the separator line. A : on the left will make a column left-aligned (this is the default). A : on the right will make it right-aligned. Both left and right :s will produce a center-aligned column. | left | center | right | |:---- |:------:| -----:| | One | Two | Three | Syntax details A header row is required and must be followed by a separator hrow with the same number of cells Cells are separated by a pipe (|) symbol Leading and trailing pipes are optional Spacing and the - characters don’t have to line up visually Comment formatting Comments support only bold, italic, code and links; in addition, a few shorthand links are available. _italic_ and **bold** text, inline `code in backticks`, and [basic links](https://example.com). !

Section id

An identifier:  productId A product name:  productName A selling cost for the consumer:  price An optional set of tags:  tags . For example: { "productId" : 1 , "productName" : "A green door" , "price" : 12.50 , "tags" : [ "home" , "green" ] } While generally straightforward, the example leaves some open questions. Here are just a few of them: What is  productId ? Is  productName  required? Can the  price  be zero (0)? Are all of the  tags  string values? When you’re talking about a data format, you want to have metadata about what keys mean, including the valid inputs for those keys.  JSON Schema  is a proposed IETF standard how to answer those questions for data. Yes. the standard uses a JSON data document to describe data documents, most often that are also JSON data documents but could be in any number of other content types like  text/xml . The  $schema  keyword states that this sch...
