The string should never be null while performing a switch case on it. String switching should only be done when there is data already present in the string form. However, switching is comparatively easily possible by using primitive data types. In java, it takes a lot of time to execute a string. If the break statement is not found, the section is jumped to another case.Break statement does not execute when used outside the switch case. The use of break statement is always done inside the switch case.If break is used, the execution will be stopped and moved to next section. It is not mandatory to use break while using switch.Switch case does not allow the use of variables.The value should always be unique otherwise it shows compile time error. The switch case doesn’t allow the use of duplicate values. It is not defined whether a switch statement will have single statement of multiple statements in the program.Switch case jumps to the next block to compare the values again. The section is executed if both the values match otherwise the section is not executed. It is also called a multi-way branch statement.Ī switch statement works in a manner in which it evaluates the value of the variable and then compares it with the block in the sequence priority. The switch statement is also called when there is a need to test the quality of the variable. It also works with wrapper classes such as Long, Int etc. Switch statements can work with a number of data types such as int, long, short, byte etc. It is just similar to the if-else block in java. Java switch statement executes a single statement out of all the statements in the block.
