K.I.S.S Java Example

This HowTo assumes you already have the JDK - Java Development Kit installed and configured in your system so you can use the javac (Java Compiler) command using your prompt. Also, this is a simple example of a Main class/method and a little code, a "HELLO WORLD!" per say. If you don't know, every Java executable must have a main method.

STEP 1

Create a text file named Kiss.java with your text editor. This will be your source code.

Oh. Everything here is case sensitive.

STEP 2

Let's make the code! Start typing right into the file Kiss.java you just have created:

class Kiss

{

   public static void main(String args[])

   {

      //This will print the meaning of K.I.S.S

      System.out.println("K.I.S.S - Keep It Simple and Short");

   }

}

STEP 3

Now, let's make this baby talk. Open your command prompt or shell or terminal (whatever), go to the location where you saved you Kiss.java file. 

Type: javac Kiss.java

If your code is okay, it will be compiled and a new file will be created: The Kiss.class - this is your code compiled to Java Bytecode. Now we just need to run:

Type: java Kiss

Your console will print:

K.I.S.S - Keep It Simple and Short

Congratulations! Now you have done your perfect Java code and can start to expand your horizons.
