Alternate Hello World
Back to the Program-A-Day homepage
ProblemThe Hello World problem has been around almost as long as modern programming has. Traditionally, when trying a new programming language or technology, developers and students like to make their new medium say hello. Because of this, the Hello World problem will be your first Java application. When executed, this application will display "Hello World!" on the console. |

SolutionThe solution is in two steps:
Next, create a Hello World java class. In your .java file under the import statement, create a public class called "HelloWorld" and a standard main method within the class. public class HelloWorld { public static void main(String[] args) { } } Now you are ready to create the body of your program. This will use System.out.println to print the message to the console. System.out.println("Hello World!"); Finally, compile and run your application. Congratulations! You've written your first Java application. It doesn't do much for now but don't worry, you'll learn much more later. Also note that it's a good idea to keep your HelloWorld.java file around since it's a convenient template for future Java applications you may write. | ||
