Undesired sample code run result in the "Executing as a Shebang File" section of the "Launching Simple Source-Code Programs" tutorial

[brlin-tw]

In the "Executing as a Shebang File" section of the "Launching Simple Source-Code Programs" tutorial the following sample code is presented:

#!/path/to/your/bin/java --source 25
 
public class HelloJava {
 
    public static void main(String[] args) {
        IO.println("Hello " + args[0]);
    }
}

with the following run instructions

./HelloJava

As the sample code expects an command argument to be provided, it will result in the following runtime error:

$ ./HelloJava 
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0
        at HelloJava.main(HelloJava:6)

I suggest:

• Replacing the sample code with a simple "Hello world" one
• Fixing the program run instructions to have a command argument available.
