Thread: if...else

Hello to all,

 public Person elementAt(int index)
    {  
    	if (maxSize < index)
    	{
    		System.out.println("Wrong Index");
    		System.out.println("PLease Insert A Value From 0 To "+ maxSize);
    	}
    	else
    		return list[index];
 
    }

On this code, an error appears keeps saying that this method must return a value.
If I just add another return after the existing one…then works
Any ideas?
Thank you in advanced!!

Your conditional if (maxSize < index) is not returning anything. You can fix the compiling error by returning null, but if you do it this way you must safeguard any code that uses this function to make sure a nullpointerexception isn't thrown.

 public Person elementAt(int index)
    {  
    	if (maxSize < index)
    	{
    		System.out.println("Wrong Index");
    		System.out.println("PLease Insert A Value From 0 To "+ maxSize);
                return null;
    	}
    	else
        {
    		return list[index];
        }
