JShell is an interactive tool for learning Java, it is a REPL (Read-Evaluate-Print-Loop) that evaluates statements , statements and expressions.
When leaving a JShell session, we want to reuse the code we previously entered into the new session. This can be done by using the command: /open [File_Path]. This command will load all code and internal commands found in the file[File_Path] provided as options.
In the following code snippet, we can use the "/open [File_Path]" command from the extension ".jsh" directory to load the source code.
<strong>C:\Users\User>jshell | Welcome to JShell -- Version 9.0.4 | For an introduction type: /help intro jshell> x | Error: | cannot find symbol | symbol: variable x | x | ^ jshell> y | Error: | cannot find symbol | symbol: variable y | y | ^ jshell> /list jshell> /open C:\Users\User\Desktop\save.jsh jshell> /list 1 : int x = 15; 2 : double y = 25.0; 3 : public int sum(int a, int b) { return a + b; } jshell> x x ==> 15 jshell> y y ==> 25.0 jshell> int result = sum(5, 7) result ==> 12</strong>
