How to return multiple objects from a Java method?

Question

I want to return two objects from a Java method and was wondering what could be a good way of doing so?

The possible ways I can think of are: return a HashMap<

Answer 1

Keep it simple and create a class for multiple result situation. This example accepts an ArrayList and a message text from a databasehelper getInfo.

Where you call the routine that returns multiple values you code:

multResult res = mydb.getInfo(); 

In the routine getInfo you code:

ArrayList list= new ArrayList();
add values to the list...
return new multResult("the message", list);

and define a class multResult with:

public class multResult {
    public String message; // or create a getter if you don't like public
    public ArrayList list;
    multResult(String m, ArrayList l){
        message = m;
        list= l;
}

}
