The decision to choose, how to create multiline strings, largely depends on the Java version we are using. If we are using Java 15 or later, then there is no reason to not use the Text Blocks. Before Java 15, String concatenation was a preferred method until the introduction ofStringJoine...

处理后的内容作为常量池中的CONSTANT_String_info条目记录在类文件中,就像字符串文字的字符一样。类文件不记录CONSTANT_String_info条目是从文本块还是字符串字面值派生的。 在运行时,文本块被计算为字符串的实例,就像字符串文本一样。从文本块派生的字符串实例与从字符串文本派生的实例无法区分。具有相同处理内容的两...
