#JAVA TEXT BLOCKS PORTABLE#
Now, the Text Blocks will have multiple lines so what is the right way to still use multi-line strings and have a portable format strings ? Solution It allows to define multi-lined string literals without breaking code indentation, by stripping the common white space prefix from the lines. After being in preview in JDK 13 and 14 with Java 15 it's the Prime Time for Text Blocks.
In format strings, it is generally preferable to use %n, which will produce the platform-specific line separator at runtime. Java 15 introduced (non-preview) text blocks feature. Text blocks were initially planned for Java 12 but this feature generated a lot of debates inside the Java Community and it's introduction has been postponed. Java Text Blocks are Java 15s solution to these problems. For example if your string to be formatted contains Linux EOL character (\n) it might be wrongly interpreted if the code is executed on Windows platform on which the EOL character is \r\n. It is a bad practice (see SpotBugs FS: Format string should use %n rather than \n) to use platform specific character/s within strings to be formatted. Since Java 1.5 the String class have a format method.Java’s String.format() is a static method that returns a formatted String using the given locale, format String, and arguments. The Text Blocks can be used by declaring the string with “””: String multiline = """ A text block is a multi-line string literal that avoids the need for most escape sequences, automatically formats the string in a predictable way, and gives the developer control over the. As of Java 15 there is a new feature called Text Block (also sometimes called Multi-Line Strings). Text blocksJava’s term for multiline stringsimmensely improve the readability of your code. Edit As of 2019, JEP 326 (Raw String Literals) was withdrawn and superseded by multiple JEPs eventually leading to JEP 378: Text Blocks delivered in Java 15.
