- The if and else keywords give you…complete flexibility in writing conditional code.…But you can sometimes write conditional code…more efficiently using the switch statement.…A switch statement examines a single value…and then compares it to multiple possibilities,…and you can control the flow of execution…based on when the two values match.…I have code in place to collect a value from the user.…I then parse that value as a primitive int.…I'll run the code for the first time…and show that in the run window…I can click here, type in a number,…and then the application finishes,…but nothing else happens.…
My goal is to examine that value.…I'll place the cursor after the existing code…and I'll add the switch keyword.…IntellJ IDEA adds parentheses.…Place the value you want to examine within the parentheses.…I'll place the value monthNumber.…Then add a pair of braces, that's the switch code block.…Now within the switch code block,…you can have one or more cases.…Each starts with the word case and then…a value that you want to match followed by a colon.…
