Automated and Manual Refactorings

Automated and Manual Refactorings

We will learn automated and manual refactoring to reduce the code junk overheard.

We'll cover the following...

Refactoring code is always a delicate task which can lead to a bigger misunderstanding if not done carefully.

In our case, the answer local variable doesn’t clarify the code, and it’s used only once. Inline (remove) the variable by replacing its use with the answerMatching(criterion) expression (line 2) in Profile.java:

Press + to interact
for (Criterion criterion: criteria) {
  boolean match = criterion.matches(answerMatching(criterion));
    if (!match && criterion.getWeight() == Weight.MustMatch) {
        kill = true;
    }
    if (match) {
        score += criterion.getWeight().getValue();
    }
    anyMatches |= match;
}

Automatic Refactoring

We could manually inline answer, but our IDE will most likely automate the inline refactoring. In Eclipse, select Refactor ▶ Inline from the main menu to inline.

The very existence of automated IDE should reinforce that ...
