Hello everyone, I'm DD, today I will continue to learn some new features of Java!
Suppose there is such a scenario, we need to make a tool. It is used to automatically generate project documents, and the documents can be viewed through the browser, so the final output must be a bunch of html files. In order to make these html files easier to read, good formatting must be maintained, the line break of the line, the indent of the indent.
Then, when organizing the final content, you might write something like this:
String html =
"<html>\n" +
"<body>\n"+
" <h1>Java 15 新特性：文本块 ｜ 程序猿DD</h1>\n"+
" <p>didispace.com</p>\n"+
"</body>\n"+
"</html>\n";Of course, maybe you can improve it and useStringBuilderorStringBufferto optimize, but no matter what you use to write, you can't escape some content that needs to be escaped, such as when splicing the content above newline\n.
Once there is a large amount of content to be escaped, it increases the complexity of our writing content. The higher the complexity, the more likely we are to make mistakes.
Therefore, a new feature has been added in Java 15: Text Blocks to help us more conveniently process multi-line string literals.
For the above string content, in Java 15, we just need to write:
String html = """
<html>
<body>
<h1>Java 15 新特性：文本块 ｜ 程序猿DD</h1>
<p>didispace.com</p>
</body>
</html>
