Java has an interactive REPL (Read-Evaluate-Print-Loop) console, jshell, that is included with the JDK.
|
|
The REPL is started by invoking: $JAVA_HOME/bin/jshell
|
|
Here is a sample session to accomplish the task.
|

|
| For an introduction type: /help
|
|
|
|
jshell> String concat(String a, String b, String c) { return a + c + c + b; }
|
|
| created method concat(String, String, String)
|
|
|
|
jshell> concat("Rosetta", "Code", ":")
|
|
