![]() 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 break statement is used to terminate the statement sequence inside the switch. ![]() Invalid expressions: switch(ef+gh), switch(e+f+g) 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.
