We will be teaching Nairalanders how to program in Java language in Just 24 hours time.
I will be your instructor, you can ask me any question and I will reply you immediately. If you don't get a reply in a minute simply ring me on 08160288961.

NOW LETS START!

HISTORY OF JAVA
James Gosling initiated Java language project in June 1991 for use in one of his many settop box projects. The language, initially called ‘ Oak ’ after an oak tree that stood outside Gosling's office, also went by t he name ‘ Green ’ and ended up later being renamed as Java, from a list of random words. Sun released the first public implementation as Java 1.0 in 1995. It promised Write Once, Run Anywhere (WORA), providing no- cost run- times on popular platforms. On 13 No vember , 2006, Sun released much of Java as free and open source software under the terms of the GNU General Public License (GPL). On 8 May , 2007, Sun finished the process, making all of Java's core code free and opensource, aside from a small portion of c ode to which Sun did not hold the copyright.

Lmao... U mean 24 hours..? Java..? u just made my day, when not html...
even a print statement will take 24 hours for some to understand...

JAVA SET UP
Before you can start writing Java programs, you need Java programming software. Several programs are available for Java, including the Java Development Kit, Eclipse, IntelliJ IDEA, and NetBeans. Whenever Oracle releases a new version of Java, the first tool that supports it is the Java Development Kit (JDK). To create the programs in TUTORIAL THREAD, you must use version 7 of the JDK or another programming tool that can work in conjunction with it. The JDK is a set of free command-line tools for creating Java software. The JDK lacks a graphical user interface, so if you have never worked in a nongraphical environment such as DOS or Linux, you’re going to be shocked—and not in a good way—when you start using the JDK. Oracle offers another free tool, the NetBeans integrated development environment, that’s a much better way to write Java code. NetBeans offers a graphical user interface, source code editor, user interface designer, and project manager. It works in complement to the JDK, running it behind the scenes, so you must have both tools on your system when you begin developing Java programs. The programs in this book were created with NetBeans, which you can download and install in a bundle with the JDK. You can use other Java tools as long as they support JDK 7.
Visit: http://www.oracle.com/us/technologies/java/jdk-7-netbeans-download-432126.html to download the latest version of NetBeans and JDK if you do not have them

Follow the installation guide on http://www.oracle.com/us/technologies/java/jdk-7-netbeans-download-432126.html although you can install your JDK and Netbeans without the guild...........Goodluck

Quite easy, don't be pessimistic. Java is not as difficult as many claim it to be.

Almighty Java in 24hrs?? Funny

Yes of cause! I hope you have your computer with you and you have downloaded Netbeans and JDK.

Writing Your First Programming Language

What you need to wite Programs
Just to refresh you, you need NetBeans and JDK (Java Development Kit) to learn Java within 24 hours.

Lets progress:

The first Java program that you create is an application that displays a traditional greeting from the world of computer science: “Saluton mondo!” To prepare for the first programming project in NetBeans, if you haven’t already done so, create a new project called Java24 by following these steps:
1. Choose the menu command File, New Project.

2. Choose the project category Java and the project type Java Application , and then click Next.

3. Enter AlphikkaTech as the project’s name. You see the error message “Project folder already exists and is not empty” if you created this project already.

4. Deselect the Create Main Class checkbox.

5. Click Finish.

Beginning the Program NetBeans groups related programs together into a project. If you don’t have the AlphikkaTech project open, here’s how to retrieve it: . Choose File, Open Project. . Find and select the NetBeansProjects folder (if necessary). . Choose AlphikkaTech and click Open Project. The AlphikkaTech project appears in the Projects Pane. To add a new Java program to the current project, choose File, New File. The New File Wizard opens.

The Categories pane lists the different kinds of Java programs you can create. Click the Java folder in this pane to see the file types that belong to this category. For this first project, choose the Empty Java File type, and click Next. In the Class Name field, enter Saluton and click Finish to create the new Java program. An empty file named Saluton.java opens in the source code editor.

Type the following into the white page. Remember Java is case sensitive, so type using lower or upper case as i have written below. example where you see the uppercase letter 'S' do not type the lower case letter 's', as we progress, you will understand why. Now type.

class Saluton {
public static void main (String[] args) {
String greeting = “Saluton mondo!” ;
System. out .println(greeting);
}
}

AlphikkaTech:

Yes of cause! I hope you have your computer with you and you have downloaded Netbeans and JDK.

will download it dis nite....does it work offline?

Yea nice

lol1
this is the first problem, are they going to install directly, no instructions to set up JRE..? just calm...

Seriously Jdk -7 u no dey do update
