Simple Java Print Statement | Java Programming Fundamentals

Introduction

In this challenge, you'll practice using the System.out.println statement in Java. This is a fundamental skill in Java programming that allows you to output text to the console. You'll modify a simple program to print a greeting message, then compile and run it.

This is a Challenge, which differs from a Guided Lab in that you need to try to complete the challenge task independently, rather than following the steps of a lab to learn. Challenges are usually a bit difficult. If you find it difficult, you can discuss with Labby or check the solution.

Create a Simple Greeting Program

Now that you've learned about the basic structure of a Java program and how to use System.out.println, let's put that knowledge into practice.

Tasks

Modify the existing SimpleGreeting.java file to print a greeting message to the console.
Compile the Java program using the appropriate command.
Run the compiled program using the appropriate command.

Requirements

Open the SimpleGreeting.java file located in the ~/project directory.
Use the System.out.println statement to print the greeting message "Hello, Java Programmer!".
Compile your program using the Java compiler in the terminal.
Run your program using the Java runtime in the terminal.
Ensure all work is done in the ~/project directory.

Example

Expected output after running the program:

Hello, Java Programmer!

Summary

In this challenge, we focused on using the System.out.println statement in Java, building upon the basic concepts introduced in the lab. We modified a simple program to print a greeting message to the console, and then compiled and ran it. This challenge demonstrates the practical application of the print statement, which is a fundamental part of Java programming, and reinforces the compilation and execution process for Java programs.
