# Run A Hello World Program In Eclipse
|
||||
|
||||
First, you'll need to create a new Java Project if you don't already have one
|
||||
to work in.
|
||||
|
||||
From there, you can add a new _Class_ to the `src` folder of that project. I'll
|
||||
call mine `Greeting.java` and the only thing it will contain is a `main`
|
||||
method.
|
||||
|
||||
```java
|
||||
public class Greeting {
|
||||
public static void main(String[] args) {
|
||||
String name = args.length > 0 ? args[0] : "World";
|
||||
|
||||
System.out.println("Hello, " + name + "!");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This method tries to read a name from the arguments given to the program at
|
||||
time of execution. If one wasn't provided the ternary falls back to `"World"`
|
||||
as the default name. It then prints the greeting to stdout.
|
||||
|
||||
To run this program, we can either select _Run_ from the _Run_ menu (which will
|
||||
result in `Hello, World!`) or we can select _Run Configurations..._ from the
|
||||
same menu and add a custom name to _Program Arguments_ under the _Arguments_
|
||||
tab.
