Java 15中的新特性“文本块(Text Blocks)”让程序员从引号和特殊字符串的泥潭里面解脱出来。 什么是文本块 文本块(Text Blocks)是一种在Java中定义多行字符串的解决方案,旨在简化多行字符串的实现方式,并提高其可读性。它们将多行字符串的创建和处理变得更加容易、直接和灵活。文本块采用 """ 分隔符,并...
在编写Java代码时,处理多行字符串常常导致可读性降低,尤其是当需要嵌入HTML、XML、SQL或JSON等格式时。传统方法如使用换行符"\n"或字符串拼接操作符"+",以及转义序列,都会让代码变得冗长且难于理解。为了提升编码效率和代码可读性,Java引入了文本块(Text Blocks)特性。文本块是一种多行字符串文字...
In general, newlines don’t have to be escaped inside text blocks. However, note that even if a source file has Windows line endings (\r\n), the text blocks will only be terminated with newlines (\n). If we need carriage returns (\r) to be present, we have to explicitly add them...

Enhances the Java language with unnamed patterns, which match a record component without stating the component's name or type, and unnamed variables, which can be initialized but not used. Both are denoted by an underscore character, _. Value: Improves the readability of record patterns by eli...
its use is inherently fragile. Optimistic read sections should only read fields and hold them in local variables for later use after validation. Fields read while in optimistic read mode may be wildly inconsistent, so usage applies only when you are familiar enough...
