Lesson 1 - The Basics of Java
Welcome to the amazing world of Java! In these lessons, you can click on the “Try It!” button to try out the code, or just use something else. If you want to create your own java online, I would use https://www.compilejava.net/.

Part 1 - Class
Java is very object-oriented, which means everything is contained in one class, also known as an object. This means that you have to put all of your code in a method, like this:

import java.io.*;
// This is a class
class MyCode {
  // This below is a method
  public static void main (String[] args) {
    System.out.println("Hello, world!"); // Prints text
  }
}

Part 2 - Import and Package
Did you see how at the top of the code, it said ?
If you didn't catch it, look at the code again:

import java.io.*;
// Code continues...

Now did you catch it?
Import is a keyword, a small word with a meaning to Java, that loads a function or class that you don't need all of the time. This keeps the main part of Java smaller, and quicker to run. These functions or classes are all stored in things called packages, that folder that look a little like this:

com
mrbumppo
java
MyCode.java(open)
click on the open button to open a file

Conclusion
I think that's just about it for now. See you soon!

Credits
I used Iconfinders's icons, and Codepad by RemoveInterview to create the examples.

Homework
Make a program that prints out your Scratch username.

Sorry it took so long! I was busy with other things.

This is a schedule I would use for the class. You can change it, just make it something like this.

#1: Explaining motion and looks blocks. Assignment making a project with the two categories.
#2 Explaining sound and pen blocks. Assignment make something with all four.
#3 Explaining Data and Events blocks. Assignment make something with all six.
#4 Explaining Control and Sensing and Operators. Assignment make a project that is a story of some sort.
#5 Explain Making blocks. Assignment make a block that makes a single block to move and have speed and how far it goes.
#6 Final Work. Make a project that is a wack-a-mole game.
