The text blocks is Java's way to simplify rendering of a string that spans multiple lines. A text block begins with three double-quote characters followed by a line terminator.^1<\/a><\/p>\n

Example: <\/p>\n

String text = """\n    The quick \n    brown fox \n    jumps over \n    the lazy dog""";<\/code><\/pre>\n
The above example is equivalent to:<\/p>\n
String text = "The quick \\n"\n    + "brown fox \\n" \n    + "jumps over \\n"\n    + "the lazy dog";<\/code><\/pre>\n
Notice who how simple the example against its equivalent.<\/p>\n
Incidental and essential white space<\/h2>\n
The java text blocks differentiates the incidental white space<\/strong> from essential white space<\/strong>^1<\/a>. Like the following example:<\/p>\n
void writeHTML() {\n    String html = """\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7<html>\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7    <body>\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7        <p>Hello World.<\/p>\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7    <\/body>\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7<\/html>\n\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7\u00b7""";\n    writeOutput(html);\n}<\/code><\/pre>\n
The dots, preceding the  tag represents the incidental white spaces while the space preceding the  tag not including the dots, represents the essential white spaces. <\/p>\n
Normally the left incidental white space can be controlled by the location of the ending delimiter of the text blocks.<\/p>\n
Trailing white space on each line in a text block is also considered incidental and is stripped away by the Java compiler^1<\/a>.<\/p>\n
Removing the ending new line of each line<\/h2>\n
Using the backslash at the end of each line will remove the implicit \\n character.<\/p>\n
String text = """\n    The quick \\\n    brown fox \\\n    jumps over \\\n    the lazy dog""";<\/code><\/pre>\n
If you output the preceding variable it will become a single line like the following:<\/p>\n
The quick brown fox jumps over the lazy dog<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
