Examining the "Boolean-Switch" in Java \_(ツ)_/
While reading through some ai-generated code today, I was caught off guard when I saw a switch statement inside of a boolean. What on earth has ai done now, I wondered. Here is the suspect: public boolean canChangeTo ( OrderStatus newStatus ) { switch ( this ) { case PLACED: return newStatus == PROCESSING || newStatus == CANCELLED ; case PROCESSING: return newStatus == SHIPPED || newStatus ==…
In a recent article, Dev.to explored the concept of using a switch statement inside a boolean in Java. The article discussed a specific example where a boolean method "canChangeTo" was implemented using a switch statement on the "this" keyword, which represents the current enum value. The article highlighted that using enums in switch statements can provide more power and efficiency compared to using if-else statements with strings.
By defining a fixed list of choices using enums, typos are avoided, and the code becomes more readable and maintainable. The article also mentioned that with the introduction of Java 14, the switch statement can be further optimized using arrow syntax, making the code even more concise. The author concluded by expressing their newfound appreciation for using switch statements with enums, as it provides a more efficient and powerful alternative to if-else statements.
