Java for Minecraft -

I have been building Minecraft Ubuntu servers for our children for a few years. I started a Neoforge modded server. I started to learn how to build custom mods and plugins. I will start with several Udemy.com courses on Java, Spigot, Maven and Minecraft.

I have learned many languages. Check out the programming page.

First Udemy module I took covered basic Java commands. It discussed primitives and non-primitives.

Double in Java is what Float is in C#. Double is 64-bit with 15 decimal places. Float is 32-bit with 7 decimal places

package com.michael.test;

// class is a page
public class Main {

    // public static void is like a paragraph
    public static void main(String[] args) {

        // Non-Primtitive
        System.out.println("This is a test");
        Integer number2 = 2;
        Double double2 = 2.2;
        Boolean boolean2 = false;
        Character character = 'D';

        // Primitive
        int number = 5;
        double decimalNumber = 102.5;
        boolean trueFalse = true;
        char letter = 's';
        System.out.println(letter);

        printMessage("Test message from other method");
        int result = printMessageInt("result");
        System.out.println(result);
        // sout is the short cut
    }

    private static void printMessage(String message) {
        System.out.println(message);

    }

    private static int printMessageInt(String message) {
        System.out.println(message);
        return 12;

    }


}

This is a test
s
Test message from other method
result
12

The second Udemy module covered Try Catch and

Main2.java

package com.michael.test;

public class Main2 {

    public SecondClass secondClass;

    public static void main(String[] args) {
        String string = "";
        //gets number 6 from here
        SecondClass secondClass = new SecondClass(6);
        secondClass.bbbbbb();
        secondClass.cccccc();

    }
}

secondClass

package com.michael.test;

public class SecondClass {
    // Constructor
    public SecondClass(int number) {
        System.out.println("Second Class has been recreated");
        // get number from main2
        System.out.println(number);
        aaaaaa();
    }

    private void aaaaaa() {
        System.out.println("A new private method has been created in SecondClass");
    }

    public void bbbbbb() {
        System.out.println("A public method is accessible in main2");
    }

    protected void cccccc() {
        System.out.println("A only accessible in the folder in main2");
    }
}

Output

Second Class has been recreated
6
A new private method has been created in SecondClass
A public method is accessible in main2
A only accessible in the folder in main2

Process finished with exit code 0
