In Scala, string interpolation is implemented by rewriting code at compile time. The compiler will treatany expression consisting of an identifier followed immediately by the open double quote of a stringliteral as a string interpolator expression. The s, f, and raw string interpolators are implemen...

In the main() function, we created two strings str1, str2 with escape sequence. Then we used the raw method of string interpolation to print a string with escape sequence character on the console screen.Scala String Programs »Scala program to concatenate formatted string using 'f' method ...
In the example, we build strings using the+operator,concatfunction, string interpolation, andprintffunction. Scala String matches Thematchesfunction tells whether the string matches the given regular expression. main.scala @main def main() =

String interpolations are written usingINTERP(sym|"x", arg, ...): INTERP(StringContext_s, LIT("Jello"), LIT(1), REF("x")) INTERP("s", LIT("Hello"), LIT(1), REF("x")) These examples print as: s"Jello${1}$x" s"Hello${1}$x"...

With Scala it’s common to embed variables in strings like this with the s string interpolator: val name = "Fred" println(s"My name is $name.") That’s cool, but when you need to format your string, Scala gives you an even more powerful tool: the f string interpolator. The Scala...
