Java Is Switch Null Safe at Joseph Galvan blog

Java Is Switch Null Safe. This article looks at changes to pattern matching for switch in its third preview: Jdk 17 adds the (preview) ability to include the previously illegal case null clause in a switch. Using java’s optional class provides null safe access to nested object hierarchies and chained method calls. As described in switch expressions, the switch blocks of switch expressions and switch statements, which use pattern or null. Case refinement and handling null cases. The decision to throw an npe when a switch expression evaluates to null is along. Using optional.map() can safely wrap chained method calls without excessive if/else checks and minimize branching. Historically, you had to check for null. In short, this design choice is in the spirit of java. In earlier versions of java, each passing of a null value to a switch statement would result in a nullpointerexception. # programming # beginners # java # softwaredevelopment.
