As your expression is a 'string' you are using a string constant. Copyin ,you can copy the string and then try to format it using ctrl+shift+ F Most often these multiline strings are not used hard coded,rather they shall be used from property or xml files. Basically, a string constant is treated the same as a string literal in Java code. Within those double quotes, certain characters have to be escaped.

Right now, Java string literals are very nice in the fact that any newline characters must be explicitly specified using escape sequences. It's a good idea in principle, but it means spending way too much time worrying about line feeds and escape sequences. First off, the Multiline annotation. Is a tab 4 spaces or 8?

How to convert a multiline Scala multiline String to an Array (or Seq)

If there is no code in your link, it probably doesn't belong here. Check out, or. It could use some updating. That syntax has been around since the seventies in Unix shells and spread. Gosling was no slouch and was probably very familiar with the Perl and shell heredoc as well as C multiline literals. This means he didn't see a burning need for them in the original Java and maybe even had a good reason to omit them. In Python, F et al you can use triple quotes, i. In Python, F et al you can use triple quotes, i. Verbatim strings are for those situations in which you need to craft strings using Cbut interpret them using something else e. It just so happens that people sometimes abuse that feature for stuff like multi-line support. Not supporting those would mean that there was something fundamentally wrong with Java's handling of text. You can't use strings to read a file with multiple lines; instead you have to write some ugly kludge. String literals is java multiline string used when programmers hardcode a string into the program. Is that something specific to this case, as in literally a multiline string. Also, I dont immediately see the advantage of a multiline string literal over the current implementation. A string literal typically results in the creation of a string object or value at run time, but strings can be constructed in other ways as well. If your program does it at runtime, it has nothing to do with string literals. The advantage of multiline string literals is that for long strings which need to be broken up, you don't have to quote and append each line like you do without support. It's purely aesthetic, and doesn't have any practical impact on the final binary. About the same arguments people are making here. Seems reasonable to me with stripMargin allowing me to keep indentation and when I use multi-line strings this is how I do it. I'm sure other people have different preferences but Scala seems to satisfy what everyone here also argues about their preference. Without the first and last newline, because that's java multiline string whitespace we'd like to ignore. Of course, you'd have to update every java parser in every java multiline string to support it. Eclipse would probably be updated in 15 minutes. You should write the JavaScript in its own. A codebase that installs, builds, and runs quickly is zen. When you have a program that outputs code, it's nice to keep the formatting. To do otherwise might be considered data loss.

This post try to show all ways and to show different ways of working with multiline strings in Java. So you will often need to paste a large, multi-line String such as a generated Lorem Ipsum text into the Java program. For this to work, what I do in my Java program is extract my email message and any attachments, and make one big Java String of them. Use a StringBuilder not String + String for multiple concatenation. Update, 2018-01-28: This is now being considered for addition to Java, read more. Not supporting those would mean that there was something fundamentally wrong with Java's handling of text. BobbyEickhoff because it's not idempotent if that word makes sense here. However, there's nothing to prevent a file on a Windows machine from having Unix- or Mac-style line separators in it.
