A Unicode character can also be represented in a regular-expression by using its Hex notation(hexadecimal code point value) directly as described in construct \x{...}, for example a supplementary character U+201
Returns a hash code value for the object. (Inherited from Object) InvokePattern() Returns the regular expression from which this pattern was compiled. JavaFinalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object...
One of the key advantages of using the Facade Pattern is that it decouples the client implementation from the internal details of the subsystem. This leads to more modular and maintainable code, where clients are shielded from changes to the subsystem’s inner workings. ...

Using pattern matching for theinstanceofoperator has been available as a production feature since Java version 16 and is usable in production code. To use this feature, I’ll just follow IntelliJ IDEA’s lead and invoke context actions on theifkeyword, which is highlighted with a yellow backgr...
