Before I start his tutorial I'd like to say it is 100% MINE i am just transferring it over from my old HF account.

Hello Everybody! My name is Daniel and I will be your Basic Command-Line Java teacher for today!

What I Expect:
1. I expect you to know nothing
2. I expect you to have an IDE
3. I expect you to WANT to learn

What You Can Expect:
1. A whole new look at JAVA
2. You should be able to make an basic-intermediate program with java

quick info: this tutorial is written WITHIN the code, where I explain each line interactively.

Lets Get Started!

Lesson 1: Hello World!

//Hello World Program
/*the {} next to the class and the method is called a code block,
* all the code for that class and/or method should be surrounded by {}
public class tutorial {//a class is the name of the file you are working in
    public static void main(String[] args){//This is the 'main' method, it is used in EVERY java program
        System.out.print("Hello World!");// this is your basic output function
        //System.out.print("Hello World!); tells Eclipse that you want it to output to the screen "Hello World!"
        //all lines of code in java (other then ones that use code blocks) end with ;
        System.out.println("Goodbye World!");
        /*the above code displays "Goodbye World!". however, as you can see it has "ln" after print
         * this tells Eclipse that you want to output this text on a new line
        System.out.println("Hello \n Goodbye");
        /*the above code displays "Hello" on one line and "Goodbye" on another (\n means new line)
         * \n is very useful because you can write long sentances but output them neatly
Lesson 2: Variables

public class tutorial {
    public static void main(String[] args){
        int INTVARIABLE = 1;//int is an integer variable (only whole numbers can be ints)
        double DOUBLEVARIABLE = 1.5;//this is a double (doubles can be decimals or whole numbers)
        String STRINGVARIBALE = "This is a string variable, it holds text";
        System.out.println(INTVARIABLE);//this will print out INTVARIABLE
        System.out.println(DOUBLEVARIABLE);//this will print out DOUBLEVARIABLE
        System.out.println(STRINGVARIBALE);//this will print out STRINGVARIABLE
        //adding ints and doubles
        int A = 2;
        int B = 2;
        int C = A + B;//adds A (2) and B (2) together
        System.out.println(C);//will print out A + B (4)
        double Q = 1.5;
        double W = 2.5;
        double E = Q + W;//adds Q (1.5) and W (2.5)
        System.out.println(E);//will print out Q + W (4)
        //Adding Strings Together To Make One Sentance
        String first = "Hello";
        String second = " Hack";
        String third = " Forum!";
        System.out.println(first + second + third);//prints out "Hello Hack Forum!"
Lesson 3: Arrays!

public class tutorial {
    public static void main(String[] args){
        //arrays are a group of variables put together
        int INTARRAY[] = {1,2,3,4,5,6,7};
        /*this array is an integer array with ints seperated with commas
         *  to declare an array you need to declare its type then its name with [] next to it
        String STRINGARRAY[] = {"Hello","Hack","Forum","!"};
        /*this is a String array, it is the same as the int array just with strings
         * This array is used to hold many strings at a time
        System.out.println(STRINGARRAY);//Prints String Array
        System.out.println(INTARRAY);//Prints Int Array
        //arrays count their objects starting at 0, so in the intarray '1' is actually in the 0 spot
        //to call a specific object we do the following
        System.out.println(INTARRAY[0]);//prints '1'
        System.out.println(STRINGARRAY[2]);//prints 'Forum'
Lesson 4: Input!

//to begin, we need to import the Scanner module
import java.util.Scanner;
public class tutorial {
    public static void main(String[] args){
        //now we need to make a Scanner object which will read what is inputed
        Scanner name = new Scanner(;//creates a scanner object named "name"
        System.out.print("Enter Your Name: ");//prints this out
        String input =;//reads what ever input follows
        System.out.println("Welcome " + input);//prints out "Welcome " and whatever you input
Lesson 5: If Statments!

//If Statement
import java.util.Scanner;
public class tutorial {
    public static void main(String[] args){
        String InputName = "John";
        Scanner name = new Scanner(;
        System.out.print("Enter Your Name: ");
        String input =;
        if (input == InputName){//if the input is exactly equal to "InputName" then...
            System.out.println("Hello " + InputName);
        else if (input != InputName){//else, if input does not equal InputName then...
            System.out.println("Hello " + input);
        else{//else, if none of the above is true then this will happen...
        int i = 1;
        int a = 2;
        if (i < a){//if i is less then a...
        else if (i > a){//else, if i is greater than a...
        else if (a >= i){//else, if i is greater than or equal to i...
            System.out.println("a >= i");
        else if (a <= i){//else, if a is less than or equal to i...
            System.out.println("a <= i");

More to come! if you have any questions you can either add me on skype (bigxexsmalls), comment here or pm me! Thanks!
