Using it at the end of any line guarantees that the line will have all space characters till '\s' is encountered. If we do not want to strip the indentation for some reason, we can use '\s' (ASCII character 32, white space) escape sequence. Escape incident space stripping to the right 'LAST_NAME' VARCHAR(100) NULL ,'STAT_CD' TINYINT NOT NULL DEFAULT 0 ) ĥ.2. |CREATE TABLE 'TEST'.'EMPLOYEE'('ID' INT NOT NULL DEFAULT 0 ,'FIRST_NAME' VARCHAR(100) NOT NULL , It suppresses the inclusion of an implicit newline character. In this case we can use line-terminator escape character which is single backslash '\'. Many times, we want to write the content into multiple lines in the program only but they are actually a single string content. Therefore, the compiler treats a single space character the same as a single TAB character, even though the TAB character might result in white space equivalent up to eight spaces.ĥ. Unfortunately, it is not difficult for the compiler to know how TAB characters are displayed in different editors. Put is at the exactly same place from where the essential indentation should pick up.Īlso, note that trailing white space on each line in a text block is also stripped away by the Java compiler. We can do this by carefully positioning the closing triple quotes to move exactly 2 tabs to the left. Lets imagine we want to give 2 tabs indentation to left for all the line in the above example. Java text blocks remove all the incidental indentations and keep only essential indentations. This should be honored to maintain the intent of indentation of text block. It is most of the time 4 or 8 spaces long. Second indentation is from start of character '(' till 'ID'. This can increase or decrease based on various factors such as formatting plugins or the developer’s choice. To talk in context, let us refer to first example.įirst indentation is from start of line till the word "CREATE" in all the lines. To perform this, JEP divides the space into incidental and essential indentations. The text blocks preserve the indentation of its content. While above text block looks very simple, still a lot of things happen under the hood. If the text content contains single or double quotes, there is no need to escape them.The opening delimiter must be on its own line. We cannot have the delimiters and text block on a single line.The opening three double-quote characters are always followed by a line terminator.Text blocks comprise multiple lines of text and uses three double-quote characters (“””) as its opening and closing delimiter.To enable this preview feature, we must use the –enable-preview and –source 14 (two hyphens) flags. It is scheduled to become a standard feature in Java 15 ( JEP 378). Java text blocks are available in Java 13 ( JEP 355) and Java 14 ( JEP 368) as preview features. It means we do not need to get into mess of explicit line terminators, string concatenations, and delimiters otherwise used for writing the normal string literals. In Java, a text block is a multi-line string literal.
