单行文本块

Question

是否可以使用Javas 文本块功能（Java15）但只写单行?

看来我是被迫写多行的

例如，我想把它写在一行中，以避免转义其中的"

String text = """<a href="https://sparkjava.com">https://sparkjava.com/</a>""";

但是编译不了，我不得不写

String text = """
    <a href="https://sparkjava.com">https://sparkjava.com/</a>""";

相反。

我是不是忽略了什么？

Answer 1

不可以，因为文本块 require a newline as part of the opening delimiter:

The opening delimiter is a sequence that starts with three double quote characters ("""), continues with zero or more space, tab, and form feed characters, and concludes with a line terminator.

所以你不能有只有一行的文本块。

Answer 2

否 - 这是不可能的，因为在 """ 运算符

之后有 mandatory 新行

由于 documentation

A text block begins with three double-quote characters followed by a line terminator. You can't put a text block on a single line, nor can the contents of the text block follow the three opening double-quotes without an intervening line terminator. The reason for this is that text blocks are primarily designed to support multi-line strings, and requiring the initial line terminator simplifies the indentation handling rules (see the section below, Incidental White Space).
