Any number of case statements can be added to the code Statements to executed in case of value 2 is true Statements to executed in case of value 1 is true The expression can be a byte, short, char, and int primitive data types. It is a multi-way branch statement that provides paths to execute different parts of the code based on the value of the expression. Rules of Switch Case Statement in Java You can only use integers, strings, and enums as the case values in a switch case statement. From JDK7, it can also be used with enumerated (Enum) data types in Java, the String class and Wrapper classes.įollowing is the Syntax of switch case in Java: switch(variable or an integer expression) The switch case is very commonly used in Java. It is a multi-way branch statement that provides paths to execute different parts of the code based on the value of the expression. The switch case is very commonly used in Java. A Switch case statement is one of the conditional statements commonly found in almost every other programming language. A code is mainly comprised of series of conditions and their possible outputs in either case. The conditions and logical statements are an integral part of any program.

Decision Making in Java (if, if-else, switch, break, continue, jump) 3. In this Java tutorial we will see one example of How to use Enum in Switch statement in Java. Switch expression must be a constant value: Decision Making in C / C++ (if, if.else, Nested if, if-else-if ) 2. Using Java Enum in the Switch case is pretty straightforward, Just use Enum reference variable in Switch and Enum constants or instances in CASE statement.Few characteristics of switch case in Java.Do we use break statement after default?.
