Newer easier ways to interact with the console in Java 23+?

I have seen mentions of new classes and methods, like this, for interacting with a console in a Java app.

I cannot find a Java JEP for that on the JEP index.

tl;dr

Yes, new console methods are being previewed in Java 24 (& Java 23).

The existing Console class, and a new IO class, offer print, println, & readln methods.

The old System.out.println ( "Hello world!" ) is supplanted by the new IO.println ( "Hello world!" ).

Details

Yes, there is a series of JEPs adding features related to the console.

• Java 24 (Early-Access)
  JEP 495: Simple Source Files and Instance Main Methods (Fourth Preview)
• Java 23 (current)
  JEP 477: Implicitly Declared Classes and Instance Main Methods (Third Preview)

This series is part of the Paving the On-Ramp effort in recent years to make Java easier for beginner students.

java.io.IO

If successful, this series of JEPs would add a new class, java.io.IO. This class offers these methods:

• static void print ( Object obj )
• static void println ( Object obj )
• static String readln ( String prompt )

Notice that these methods are static. So we can use them without instantiating an object.

So the familiar System.out.println ( "Hello world!" ); becomes:

import java.io.IO;
…
IO.println ( "Hello world!" );

Or, be even more brief with a static import.

import static java.io.IO.println;
…
println ( "Hello world!" );

java.io.Console

These java.io.IO methods are implemented by calling upon the Console object returned from System.console(). So that Console class gains new methods, with the same signatures.

Caveat: These are preview features, subject to change or removal.

Try these out in an early-access build of Java 24 based on the OpenJDK codebase. See the early-access Javadoc for Java 24.
