Java Null In Switch at Sherry Joanna blog

Java Null In Switch. Traditionally, the switch throws a nullpointerexception when the value is null. Java se 17 has a preview feature that enhances switch expressions to allow. You can't switch on strings and other data types that can be null. If you try to switch on a null value you will get a nullpointerexception. Unconditional patterns still match null, but switch won’t let it get. You can use primitives (int, char, short, byte) and string (strings in java 7 only) in switch. This behavior is still present for existing switch statements, which do not make use of patterns. Jdk 17 adds the (preview) ability to include the previously illegal case null clause in a switch. The case null clause in switch. Check i in separate condition before. Fortunately, jep 427 proposes to change that unpleasant situation. When a switch expression evaluates to null and there is a corresponding null case label, the code associated with that label executes, providing a graceful workaround to prevent nullpointerexceptions. In java switch statements, null case labels offer a unique way to handle edge cases involving null values.
