6/30/2023 0 Comments Switch case java string![]() Now let's see some examples for more understanding. However nested switch statements should be avoided as it makes program more complex and less readable. Nesting of switch statements are allowed, which means you can have switch statements inside another switch.The default case can be used for performing a task when none of the cases is true. A switch statement can have an optional default case, which must appear at the end of the switch.If no break appears, the flow of control will fall through to subsequent cases until a break is reached. When a break statement is reached, the switch terminates, and the flow of control jumps to the next line following the switch statement.When the value being switched on is equal to a case's value, then the statements following that case will execute until a break statement is reached.See the following section for structure and examples of using the switch case statement. Switch statements with String cases have been implemented in Java SE 7, at least 16 years after they were first requested. The break statement is necessary to exit the switch statement (see explanation in the first example). The value of a case must be a constant value and it must be of the same data type as the output value of the test expression in the switch statement. The switch statement also works with the String class of Java, enumerated types, and a few special classes.Object game 'Hockey' // It is not allowed String game 'Hockey' // It is OK. In order to use string, you need to consider the following points: It must be only string object. Each case is followed by a value and a colon. String in Switch Statement In Java 7, Java allows you to use string objects in the expression of switch statement. You can have any number of case statements within a switch.The expression's output value statement must be of byte, short, char, int or string. Switch case statement is used when we have number of options (or choices) and we may need to perform a different task for each choice.The following rules apply to switch case statements: Switch statement will ends automatically. In default case, break is not required because it the last case after that the If text expression's output value does not match with any of the case's value then statements following the default (optional case) will execute. In the above syntax, we will write our test expression in place of the expression if the test expression's output value matches with any of the case's value then the statements following thatĬase are executed. ![]() ![]() If the value of the expression matches the value of a case. ![]() Pick one argument which you want and use it as the String in the switch. you can have any number of case statements. In switch(expression), the value of the expression is compared with the values of all the cases. You can use switch with String also, however youre trying to use a String array. ![]()
