.Problem 2: In Java, && and || are short circuit operators, meaning they evaluate only what is necessary. If the expression p is more likely to be true than the expression q, which one should you place on the left of each operator to avoid doing extra work? Explain why.
a) left of the && expression:
b) left of the || expression:
In the case where the expression p is more likely to be true than the expression q. You should place p on the left side of both the java && (logical AND) and || (logical OR) operators.
a) Left of the && expression:
By placing p on the left side of the && operator.
If p evaluates to false. Then the overall result of the expression will always be false regardless of the value of q.
Since p is more likely to be true. If it indeed evaluates to true, the evaluation of q is skipped entirely due to the short-circuit behavior of the && operator.
This helps in avoiding unnecessary evaluation of q when it is less likely to affect the final result.
b) Left of the || expression:
Similarly, by placing p on the left side of the || operator.
If p evaluates to true then the overall result of the expression will always be true regardless of the value of q.
Since p is more likely to be true. If it evaluates to true, the evaluation of q is skipped due to the short-circuit behavior of the || operator.
This avoids unnecessary evaluation of q when it is less likely to affect the final result.
In both cases, by placing the expression more likely to be true on the left.
You take advantage of the short-circuit behavior of the operators to minimize the amount of work done and improve the efficiency of your code.
