Here’s a little example of how to use a break in a Scala for loop:
This is an excerpt from the Scala Cookbook (partially modified for the internet). This is Recipe 3.5, “ Scala: How to use break and continue in for loops (and while loops)”
You have a situation where you need to use a
continue construct, but Scala doesn’t have
Scala FAQ: Can you share some examples of how to implement break and continue functionality in Scala?
Sure. The example Scala code below shows both a break and a continue example. As you can see from the
import statement, it uses the code in the Scala
To understand how this works, let's first look at the code, and then the output. First, here's the code:
AppleScript FAQ: How do I break a long line in AppleScript?
When you program in AppleScript, you can very easily start creating programs with very long lines, which are hard to read. And AppleScript doesn't like it when you use carriage returns to break your long lines, which is a bit of a bummer.

Perl loop break FAQ: How do I break out of a Perl loop?
Problem: You're writing some Perl loop code (for, foreach, or while), and you have a condition where you need to break out of your loop early, and you quickly find out that Perl doesn't have a 'break' operator.
The Perl "break" statement

Java String FAQ: How do I split a String into substrings?

LaTeX FAQ: How can I prevent line breaks from occurring in my LaTeX documents?

This keeps "Mr. John Doe" on the same line when your document is created.
