Java while(condition doesn't reach)?? Why

Question

Why is it when I do this

while(word.charAt(left) == word.charAt(right) && left >= 0 && right < word.length()){
            left--;
            right++;
        }

its says in the while conditions "left >= 0 && right < word.length()" condition doesn't reach, but when I do it like this

 while(left >= 0 && right < word.length() && word.charAt(left) == word.charAt(right)){
            left--;
            right++;

        }

The conditions are met. Is there an order for while(loop conditions)???

Answer 1

The order does matter as conditions are checked from left to right. You're getting that message because if the previous condition evaluates to true, then those two conditions

left >= 0 && right < word.length()

will always evaluate to true. You probably want the latter (since you would want to check all the conditions).
