![]() ![]() Text block introduces 2 new escape sequences: \ for line continuation and \s for not removing trailing spaces.įor the detailed specification of Text block feature, I recommend you to read JEP 378.A text block is declared inside the opening 3 double quotes and closing 3 double quotes, and the content begins on the next line.Text block is not raw string, because the Java compiler will process a text block: normalize line terminators, remove incidental white spaces (both leading and trailing) and interpret escape sequences.Text block allows the creation of multi-line String literals a lot easier. ![]() To summary, below are some key points you should keep in mind: """ Okay, so that’s to help you understand text block - a new, standard feature in JDK 15. ![]() Print this text block you will see the following output: This is an example of a text block in Java: """ You see, this text block uses the \””” to represent 3 double quotes and \t for a tab. This is an example of a text block in Java: For example, if you want to use 3 double quotes in a text block, you must escape it like this: String textBlock = """ But with text blocks, I think we don’t have to use escape sequences in most common cases. This is much more convenient than using String concatenation operators ( ) for multi-line String literals.You can also use escape sequences in a text block as in a regular String literal. You can see the \ character is used at the end of each line to tell Java compiler that the String literal continues on the next line (do not interpret new line characters). SELECT p FROM Product p WHERE p.name LIKE %?1% \ All quotation marks used to be curly before the.

Let’s consider an example below: String json = "Awesome! So programmers won’t have to write extra code just to remove the unwanted spaces.
