You can check also if Java is installed successfully on your PC or not

Go To The Command Prompt and type “javac” and press Enter.

If you get message like something that tells Java is not recognized as a internal or external commend then it means Java is not installed on your PC.

And If you get no message like this after pressing Enter button that means Java is installed your computer.

HOW TO RUN FIRST JAVA PROGRAM

Now its time to run and test our first Java Program. We at initially use Command Prompt for Testing of Java and write codes on Notepad and save the written code with “ .java ” extension.

So lets write a first Java Program that will be of course  ” Hello World ” again.

Here is the code if you want to copy and paste :

---

class Hello
{
public static void main(String[] args)
{
System.out.println(“Hello world!”);
}
}

Write this code on Notepad and save with .java ext.

Now its time to run this program.  For this we will go to Command Prompt

you need to go to the directory where your java is present and use command ” javac  ( and file name with ext) ” 

To Run Program Type  ” java  (and filename )”
