How to define a switch statement in JShell in Java 9?

JShell is based on the REPL (Read-Evaluate-Print-Loop) introduced in Java 9. This tool can be used to execute simple statements, evaluate it, and prints the result.

A switch statement can test multiple conditions just like an else clause and handles the default possibility. The default clause can be executed when none of the cases match, and a break statement can be used to break out of switch after a successful match.

In the below code snippet, we can define the switch statement in JShell.

Snippet-1

jshell> int i = 10; i ==> 10 jshell> switch(i) { ...> case 1 : System.out.println("1"); ...> case 10 : System.out.println("10"); ...> default : System.out.println("default"); ...> } 10 default jshell> int i = 1; i ==> 1 jshell> switch(i) { ...> case 1 : System.out.println("1"); ...> case 10 : System.out.println("10"); ...> default : System.out.println("default"); ...> } 1 10 default

In the below code snippet, we can define a switch statement with a break in JShell.

Snippet-2

jshell> switch(i) { ...> case 1 : System.out.println("1"); break; ...> case 10 : System.out.println("10"); break; ...> default : System.out.println("default"); break; ...> } 1
