Smell code identification

b) Consider the following java code (method) compares 2 numbers and returns true if the first is greater and false otherwise. Do you think there is bad smells in this code, if yes than identify its type, and write a new code by using refactoring approach to remove the code smell. public boolean max(int a, int b) { if(a > b) { return true; } else if (a == b) { return false; } else { return false; } }

1. name of function is not compatible for it's functionality. 2. return a > b; this one line can do what whole your code do.

else-if code block is unnecessary. This is a third thread of same question. Other two being https://www.sololearn.com/Discuss/2599334/?ref=app and https://www.sololearn.com/discuss/2599349/?ref=app Do NOT repeatingly post the same question!

public boolean max(int a, int b) { return (a > b); } The "smell" came from unnecessary `else...if` and `else` block. The function is supposed to return 'true' ONLY when <a> is greater than <b>, so we can do this simply by returning the evaluation result for expression (a > b).
