    Default return statement confusion

    ok so i have a problem here...

    i have 2 classes and one is calling another:

    public class DinnerMenu implements ItemListener
    {
     
    ... //beginning of code
     
    soup watery = new soup();
    int dollar = 0;
     
    public void itemStateChanged(ItemEvent e)
    {
    	dollar += watery.getchangedollar();
    	... //rest of code
    }
     
    ... //rest of code
     
    }

    and the second class is:

    public class soup
    {
    	... // beginning of code
     
    public int getchangedollar()
    {
    	if (van.getStateChanged()==true)
    		return 2;
    	else if (veg.getStateChanged()==true)
    		return 3;
    	else if(broth.getStateChanged()==true)
    		return 4;
    }
     
    ... //rest of code
     
    }

    i get an error: "missing return statement"

    why?

    also i tried to fix it by changing the second class:

    public class soup
    {
    	... // beginning of code
     
    public int getchangedollar()
    {
    	int x;
     
    	if (van.getStateChanged()==true)
    		x=2;
    	else if (veg.getStateChanged()==true)
    		x=3;
    	else if(broth.getStateChanged()==true)
    		x=4;
     
    	return x;
    }
     
    ... //rest of code
     
    }

    and there i get another error: "x might not have been initialized"

    any help on why im getting these errors would be great, thanks

    Dont be that guy

    My guess is that it is upset as you haven't stated what to return in the event that all of your if and else if statements fail. Basically, I think it wants an else statement.

    sweet, it worked... i guess it requires a return statement for all possibilities, so having an else statement with noting in it gave me an error... had to put return 0; for it.

    thanks

    intialize the x value to 0 so that can remove the second error
