Java is one of the most widely used programming languages used today. The switch statement is used to test the equality of a variable against several values specified in the test cases. Thus, it is like an if-else-if ladder statement. The switch case in java executes one statement from multiple ones.

("elective courses : Software Engineering") ("elective courses : Advance Maths, Algebra") Here is a Java program to demonstrate nested switch case statement: As a switch case defines its block, the case constraints in the inner switch do not conflict with those in the outer switch. This is known as a nested switch case in java. Java program to demonstrate switch case with multiple cases without break statements.Ī switch case can be used as a part of an outer switch's statement sequence.

This code displays whether a month has 30, 31, or 28 days: There can be multiple cases without a break statement between them as it is desirable in some cases, such as the given one. On execution without a break statement, control will continue into the next case. Since the break statement is optional, we can omit it. } Execution while Omitting the Break Statement When none of the cases is true, a default statement is used, and no break is needed in the default case. The switch block has case statements whose values must be of the same type of expression The syntax of the switch statement is as follows: Nesting is allowed, but it makes the program more complex.įor example, the code below uses the monthly number to calculate the month name:ĭefault: ("In next half").The default statement can appear anywhere inside the switch block, but a break statement should follow it if the default is not in the end.If the break statement is omitted, the execution will continue into the next test case.The test case values need not be in order (ascending or descending).The break statement is used to terminate the statement sequence inside the switch.Invalid expressions: switch(ef+gh), switch(e+f+g) The value for the cases needs to be literal or constant but not a variable.The data type of variable in the switch needs to be the same as all test cases' values.There are some things to be remembered while using switch case in java: Otherwise, the code specified for the matched test case is executed. If there is no match, the default keyword, if specified- the associated code executes. The value of the expression is matched with each test case till a match is found. Switch is provided with an expression that can be a constant or literal expression that can be evaluated. switch case in Java works like an if-else ladder, i.e., multiple conditions can be checked at once.

The case value can have a default label which is optional.

If a break statement is not found, it executes the next case. When control reaches to the break statement, it jumps the control after the switch expression.

Each case statement can have a break statement which is optional.

The Java switch expression must be of byte, short, int, long (with its Wrapper type), enums and string.

In case of duplicate value, it renders compile-time error. The case value must be literal or constant.

The case value must be of switch expression type only.

There can be one or N number of case values for a switch expression.

In other words, the switch statement tests the equality of a variable against multiple values. Since Java 7, you can use strings in the switch statement. The switch statement works with byte, short, int, long, enum types, String and some wrapper types like Byte, Short, Int, and Long. The Java switch statement executes one statement from multiple conditions.
