How to Run Java Program

Java is a popular, high-level, object-oriented programming language that was developed by James Gosling and his team at Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It is widely used for developing various kinds of software, including web applications, desktop applications, mobile applications, games, and more.

Step by Step Implementation

To run a Java program, you need to follow these steps:

Step 1: Install Java Development Kit (JDK) on your computer. You can download the JDK from the Oracle website or any other reliable source.



 

Step 2: Write your Java code in a text editor such as Notepad or any other code editor. Save the file with a .java extension and file type as ‘All files’ in the desired location.



Step 3: Open the command prompt (Windows) or terminal (Mac or Linux).



Step 4: Navigate to the directory where you saved your Java code using the “cd” command.



Step 5: Compile your Java code by typing “javac [filename].java” in the command prompt/terminal. This will create a .class file in the same directory.




Step 6: Run your Java program by typing “java [filename]” in the command prompt/terminal. The program will execute and produce the output.
