To get started, create an xml file activity_main.xml with following line of code: In the following example, if expr evaluates to Bananas, the program matches the value with case case Bananas and executes the associated statement. switch statements can have a cleaner syntax over complicated if else statements.

The variable used in a switch statement can only be integers, convertable integers (byte, short, char), strings and enums. We use the break keyword to terminate the code whenever a certain condition is met (when the expression matches with a case). Testing Expression: Switch statement can not be used to test expression. If all the cases do not match the expression, then the code block defined under the default keyword gets executed. The cases inside the switch statement are fixed values and can’t be a boolean. The switch case statement in Java The switch block, which is the body of switch statement may contain one or more case labeled statements. Switch statements can be used for fixed data values. use new form of switch label (case L ->): The code to the right of a 'case L ->' switch label is restricted to be an expression, a block, or (for convenience) a throw statement.
