Welcome! Today, we're exploring Scala's special instructions: Conditional Looping, along with constructs that offer similar capabilities to Scala's break
and continue
. We know that loops enable code execution multiple times. Conditional looping, combined with Scala's powerful control constructs, enhances loop control, leading to flexible, efficient code. Put on your explorer's hat, and let's get started!
Scala's if
statement sets condition-based actions for your code. Consider this straightforward example where the if
statement determines which message to print based on the value of temperature
:
We can also evaluate multiple conditions using else if
. In other words, "If the previous condition isn't true, then check this one":
Scala doesn't have a direct break
statement, but we can achieve similar functionality using scala.util.control.Breaks
. Here’s how you can exit a loop prematurely when a condition is met:
Scala doesn't have a continue
statement, but we can achieve similar behavior using conditional expressions within the loop:
By integrating the tools we've discussed, you can write flexible loops. Here's how you would conclude a loop once you find "Charlie" using Scala:
Congratulations! You are now more familiar with Scala's if
statement, using breakable
for loop control, and alternatives to continue
statements, alongside their applications with loops. It's time to solidify your learning with upcoming practice exercises. Happy coding in Scala!
