![]() Similarly, the code of case value2 is executed if expression. First the variable, value or expression which is provided in the switch parenthesis is evaluated and then based on the result, the corresponding case block is. ![]() Only helps us write more readable code but the compiler will likely generate more efficient bytecode as compared to the if-then-else statement. Java switch case uses String.equals() method to compare the expression value with case values, so it will throw NullPointerException if passed value is null. Java switch Statement If expression matches with value1, the code of case value1 are executed. ![]() If there is a match, the associated block of code is executed. The value of the expression is compared with the values of each case. It is a small but useful feature which not This is how it works: The switch expression is evaluated once. Since String is one of the most used classes in Java, and almost every. The switch case matching is case sensitive, so java will not match. After the release of java 7 we can even use strings in the cases. But Java Switch and case statement have a limitation, you cannot use String in them. Java switch case with string is more readable than the multiple if-else if-else blocks. Java Switch case uses String. These multiple values that are tested are called cases. Java switch case String is case sensitive, the output of example confirms it. The switch statement when used with a String uses the equals() method to compare the given expression to each value in the case statement and is therefore case-sensitive and will throw a NullPointerException Java switch case String make code more readable by removing the multiple if-else-if chained conditions.
