Escaping quotes in Groovy strings

Groovy supports strings enclosed in single or double quotes and between slashes. If we use single quotes we don't have to escape double quotes. And if we use double quotes we don't have to escape single quotes. We can use the slashes if we have a string with both double and single quotes and we don't want to escape them.

Double Quotes

They are used just like Java double quotes, except that we can also substitute variables inside double quotes (string Interpolation):

Declaring and initializing char variable

As seen above single quotes can be used for string. So when it comes to initializing a variable of type 'char' we cannot use single quotes along with with def or with no type (check out this tutorial on types). In that case we must:

Triple Single quotes

Triple quotes are used as triplets of single quotes. They can be used for multiline string:

Triple double quotes

Triple double quoted strings behave like double quoted strings, with the addition that they are multiline.

Slashy string

Does Groovy support arrays?

Groovy has always supported literal list/array definitions using square brackets and has avoided Java-style curly braces so as not to conflict with closure definitions.

Can you escape a quote with a backslash?

Can groovy expressions be interpolated?

Any Groovy expression can be interpolated in all string literals, apart from single and triple- single-quoted strings. Interpolation is the act of replacing a placeholder in the string with its value upon evaluation of the string. The placeholder expressions are surrounded by $ {}. The curly braces may be omitted for unambiguous dotted expressions, i.e. we can use just a $ prefix in those cases. If the GString is ever passed to a method taking a String, the expression value inside the placeholder is evaluated to its string representation (by calling toString () on that expression) and the resulting String is passed to the method.
