i run a simple helloworld program but the output shows some square characters. what is it? why i cannot see the print message?

I'm really not sure if this will help you but have you tried having your main method like this?

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }

Seem odd to have a square character next to the "args" in your main method.

Looks like a font problem, have you tried different fonts?

I think there are a couple issues going on here:

First, when you declare this class you might want to retrieve data stored in the class from an accessor method. So you would define your class, your class-level attributes, and some methods and you would define a class to test this that would call a method to retrieve your string. Otherwise use something like this:

public class HelloWorld
{
public static void main( String[] args )
{
String s = "Hello World!";
System.out.println( s );
}
}

Second, I would agree that your font might be screwed up. I'm not sure which IDE you're using, but you should be able to change it to support your character map.

However, be aware that a class is not something that should be run standalone in most implementations - if I were you I'd define a class like this:

public class HelloWorld
{
public String getHello()
{
String s = "Hello World!";
return s;
}
}

and define a class to evaluate this class like this:

public class TestHelloWorld
{
public static void main( String[] args )
{
HelloWorld hw = new HelloWorld();
System.out.println( hw.getHello() );
}

}

That's not 100% accurate, but it should give you enough to start from. I'd also recommend checking out the Java Docs in your IDE - most IDEs have decent documentation built in.

Just in case anyone is (re)searching NetBeans compatibility on OpenBSD, other reports have been posted to misc@ about similar square characters being displayed in the output window:

Remember, http://marc.info/ is a wonderful resource for the Open Source community. OpenBSD users should consider this as an authoritative resource on par with the manpages. Use them both, & use them often.
