Java is one of the most widely used programming languages used today. The switch statement is used to test the equality of a variable against several values specified in the test cases. Thus, it is like an if-else-if ladder statement.

On execution without a break statement, control will continue into the next case. Since the break statement is optional, we can omit it. } Execution while Omitting the Break Statement When none of the cases is true, a default statement is used, and no break is needed in the default case. The switch block has case statements whose values must be of the same type of expression The syntax of the switch statement is as follows: Nesting is allowed, but it makes the program more complex.įor example, the code below uses the monthly number to calculate the month name:ĭefault: ("In next half").The default statement can appear anywhere inside the switch block, but a break statement should follow it if the default is not in the end.If the break statement is omitted, the execution will continue into the next test case.The test case values need not be in order (ascending or descending).

The value for the cases needs to be literal or constant but not a variable.The data type of variable in the switch needs to be the same as all test cases' values.There are some things to be remembered while using switch case in java: Otherwise, the code specified for the matched test case is executed. If there is no match, the default keyword, if specified- the associated code executes. The value of the expression is matched with each test case till a match is found. Switch is provided with an expression that can be a constant or literal expression that can be evaluated. The switch case in Java works like an if-else ladder, i.e., multiple conditions can be checked at once.
