System.out.println("Hello"); = (No explicit return value)

Question

Tried printing Hello. But nothing was printed on console. It returned the value as (void). Suggest a solution

Attached the expression as image.

@Service("DetailsDAO") 
public class DetailsDAOImpl implements DetailsDAO {

    private static final Logger logger = Logger.getLogger(DetailsDAOImpl.class);

    @Override 
    public List < DetailsVO > getDetails(String name) {
        System.out.println("Hello");
        logger.info("Hello");
        List < DetailsVO > detailList = new ArrayList < DetailsVO > ();
        DetailsVO detVo = new DetailsVO();
        detVo.setAdd1("abc");
        detVo.setAdd2("qwe");
        detailList.add(detVo);
        return detailList;
    }
}

Answer 1

Your problem is not very clear and i suggest you post some code.

A simple Hello World program looks like this:

public class Main {

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

Please note that System.out.println does not return anything, it simply does what its name means: Print a line on the console.
