Question

I am trying to dig my way through the strict Java methods and operators, but now, trying to ‘translate’ a piece of PHP code to Java (Android), I’m kinda stuck.

In PHP:

if ($row['price']>'0'){
  (.. do something if price is defined - and higher than zero ..)
}

The problem is that $row[‘price’] may be empty (in Java: null?) or contain ‘0’ (zero).
But how can I code that in Java in a smart and not too complicated way?

Answer 1

Assuming you got the price string in a variable price

String price = <get price somehow>;    
try {
    if (price != null && Integer.valueOf(price) > 0) {
        do something with price...
    }
} catch (NumberFormatException exception) {
}
