![]() ("Your grade is " + grade) Ĭompile and run the above program using various command line arguments. The default case can be used for performing a task when none of the cases is true. If no break appears, the flow of control will fall through to subsequent cases until a break is reached.Ī switch statement can have an optional default case, which must appear at the end of the switch. 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 variable being switched on is equal to a case, the statements following that case will execute until a break statement is reached. The value for a case must be the same data type as the variable in the switch and it must be a constant or a literal. Then you code one or more statements that you want executed if the value of the switch expression equals the constant. Each case is followed by the value to be compared to and a colon. It can be used to select one of several possible execution paths and is typically used to replace multiple if-else-if statements or a series of nested if statements. We also talked about the switch statement's expression, cases, and default keyword in Java along with their use cases with code examples. The switch statement is a control flow statement used in Java, which means that it determines the flow of program execution. ![]() The working of switch statement is very similar to. In this article, we saw how to use the switch statement in Java. You can have any number of case statements within a switch. switch statement evaluates its expression and then selects the matching block. The variable used in a switch statement can only be integers, convertable integers (byte, short, char), strings and enums. The variable you want to check goes between the round. The switch statement evaluates an integer expression or. The following rules apply to a switch statement − So you start with the word switch, followed by a pair of round brackets. The switch statement is a control flow statement used in Java, which means that it determines the flow of program execution. ![]() Switch statements are a form of conditional statement used to control the flow of a program. You can have any number of case statements. The Java switch statement is used to evaluate a statement against multiple cases and execute code if a particular case is met. Each value is called a case, and the variable being switched on is checked for each case. A switch statement allows a variable to be tested for equality against a list of values. ![]()
