Java Runtime Environment (JRE) for WacOS

About

WacOS will optionally allow you to install most versions of Java along with the system, either at installation or after. A JRE will be maintained here that handles Java throughout the system.

This feature is currently in development, and is in the planning phase.

Test program

Use this Hello World program to test your installation:

public class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); // Prints the string to the console.
    }
}

Or do a more advanced test:

// This is an example of a single line comment using two slashes

/*
 * This is an example of a multiple line comment using the slash and asterisk.
 * This type of comment can be used to hold a lot of information or deactivate
 * code, but it is very important to remember to close the comment.
 */

package fibsandlies;

import java.util.Map;
import java.util.HashMap;

/**
 * This is an example of a Javadoc comment; Javadoc can compile documentation
 * from this text. Javadoc comments must immediately precede the class, method,
 * or field being documented.
 * @author Wikipedia Volunteers
 */
public class FibCalculator extends Fibonacci implements Calculator {
    private static Map<Integer, Integer> memoized = new HashMap<>();

    /*
     * The main method written as follows is used by the JVM as a starting point
     * for the program.
     */
    public static void main(String[] args) {
        memoized.put(1, 1);
        memoized.put(2, 1);
        System.out.println(fibonacci(12)); // Get the 12th Fibonacci number and print to console
    }

    /**
     * An example of a method written in Java, wrapped in a class.
     * Given a non-negative number FIBINDEX, returns
     * the Nth Fibonacci number, where N equals FIBINDEX.
     * 
     * @param fibIndex The index of the Fibonacci number
     * @return the Fibonacci number
     */
    public static int fibonacci(int fibIndex) {
        if (memoized.containsKey(fibIndex)) return memoized.get(fibIndex);
        else {
            int answer = fibonacci(fibIndex - 1) + fibonacci(fibIndex - 2);
            memoized.put(fibIndex, answer);
            return answer;
        }
    }

Feature translation notes

The exact system requirements are not a forced emulation option. The WacOS system is designed to be lighter, but you can adjust it to match MacOS.

WacOS equivalents of programs are included.

Malicious methods (such as DRM/TPM) are NEVER included with WacOS, not even as an open source recreation.

Please raise an issue if any other clarification is needed.

Guesthouse repository

This is a guesthouse repository, and not a home repository, as development mainly stays on the main WacOS side. This is just the guesthouse that the project retreats to at times. If you are already in this repository, the link is likely recursive, and will reload the page.
