![]() The switch Statement of the Java Language Specification. Then the switch statement compares the resulting value with the next ValueX (in the order in which they are listed). By contrast, execution within a SWITCH statement falls through to the next statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. Execution exits the CASE statement at the end of the matching statement. Both instructions function by popping the stack. It is like an if-else-if ladder statement. Switch-case statements are internally implemented with either tableswitch or lookupswitch bytecode instructions. In simple words, the Java switch statement executes one statement from multiple conditions. A Java switch statement is a multiple-branch statement that executes one statement from multiple conditions. In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change. It's possible to group several conditions in the same case statement using the mechanism of fall through allowed by switch statements, it's mentioned in the Java tutorial and fully specified in section ยง14.11. The switch statement is a multi-way branch statement.
