When a method loops multiple over the same set of data, whether it’s a list or a set of numbers, it is highly likely that the method could be made
more efficient by combining the loops into a single set of iterations.
Noncompliant code example
public void doSomethingToAList(List<String> strings) {
for (String str : strings) {
doStep1(str);
}
for (String str : strings) { // Noncompliant
doStep2(str);
}
}
Compliant solution
public void doSomethingToAList(List<String> strings) {
for (String str : strings) {
doStep1(str);
doStep2(str);
}
}
