java conditional operator and different types

Question

I have two methods in the Item Class:

public void setValue(String v);
public void setValue(Double v);

and I want to use Cond

Answer 1

IF you want to go with the ternary operator only following code will solve your problem. For testing I have put false as the default value you can put your conditional expression.

public class st1 {
    public static void main (String []args) {
        Item i = new Item();
        i.setValue (false?"test":0.0);
    }
}

class Item {
    private String str;
    private double d;
    public void setValue (Object str) {
        try {
            d = Double.parseDouble (str.toString());
            System.out.printf ("Double type : %f", d);
        } catch (NumberFormatException ne) {
            this.str = str.toString();
            System.out.printf ("String type : %s", this.str);
        }
    }
}
