리팩토링 : Split Loop

작자 : Martin Fowler

조건

두가지를 수행하는 루프가 있다면

적용

루프를 분리하시오.

적용전

void printValues() {
	double averageAge = 0;
	double totalSalary = 0;
	for (int i = 0; i < people.length; i++) {
			averageAge += people[i].age;
			totalSalary += people[i].salary;
	}
	averageAge = averageAge / people.length;
	System.out.println(averageAge);
	System.out.println(totalSalary);
}

적용후

void printValues() {
	double totalSalary = 0;
	for (int i = 0; i < people.length; i++) {
			totalSalary += people[i].salary;
	}

	double averageAge = 0;
	for (int i = 0; i < people.length; i++) {
			averageAge += people[i].age;
	}
	averageAge = averageAge / people.length;

	System.out.println(averageAge);
	System.out.println(totalSalary);
}
