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 ...
Switch statement in java I bumped into a question just now about a switch statement: int a = 2; int x = 0; switch(a){ case 1: ++x; case 2: ++x; case 3: ++x; default: ++x; } System.out.print(x); //output = 3 I understand that x in this case is being pre incremented...

Instead of writing many if..else statements, you can use the switch statement.The switch statement selects one of many code blocks to be executed:SyntaxGet your own Java Server switch(expression) { case x: // code block break; case y: // code block break; default: // code block } ...
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 ...
Switch Statement in Java It is used to tests multiple conditions, which act like an If-Else-If ladder. Switch statement is used with byte, short, int, enum, long, String and their corresponding wrapper classes. Thus, it tests the condition against multiple cases. ...
