In addition, it should be noted that for the function of pattern matching in switch expressions, the implementation in JDK 17 is still the preview version, so understanding is the main thing. It is not recommended for use in the official environment at present, and the possibility of further ...
Gavin Bierman, a consulting member of the Oracle technical staff based in the UK, explained the concepts behind pattern matching in general and, more specifically, pattern matching forswitch. Bierman, who managed the JEP 406 process, works in the Java Platform Group helping design the next versio...
Generally, pattern matching is referred to as testing some data to see if it has a particular structure and verifying it is a match or not, as we do in regular expressions. The following JEPs enhanced this Java feature to be used withinstanceofoperator to make it more concise and robust. ...
不过有一点不同,在Java的Pattern Matching中,它并没有把原变量进行Pattern Matching处理,而是允许你在后面定义一个新变量来做Pattern Matching。 Switch与Patterm Matching 其实,Java的Pattern Matching除了可以在instanceof中使用以外,还可以在另一个场景中,Switch中也能使用。 不过Pattern Matching与Switch的结合,仍然是...
