A unique characteristic of the switch statement in Java is the ‘fall through’ behavior. When a match is found in the case values, and there’s no break statement to terminate the current case, Java will execute all subsequent cases until it encounters a break statement or reaches the end ...
Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java 12. Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatem...

The fall-through behavior can lead to subtle bugs when you simply forget to include abreakstatement. Consequently, the behavior of the program could be incorrect. In fact, the Java compiler warns you of suspicious fall through if you compile with- Xint:fallthrough. The issue is also picked ...
Java Switch Statements Instead of writingmanyif..elsestatements, you can use theswitchstatement. Theswitchstatement selects one of many code blocks to be executed: SyntaxGet your own Java Server switch(expression){casex:// code blockbreak;casey:// code blockbreak;default:// code block}...
It is not necessary to break the last case in a switch block. The block breaks (ends) there anyway. Note:If you omit the break statement, the next case will be executed even if the evaluation does not match the case. The default Keyword ...
