Any statement or block of statements can be identified by a label, but those labels should be used only on while
,
do-while
and for
statements. Using labels in any other context leads to unstructured, confusing code.
Noncompliant code example
myLabel:if (i % 2 == 0) { // Noncompliant
if (i == 12) {
print("12");
break myLabel;
}
print("Odd number, but not 12");
}
Compliant solution
myLabel:for (i = 0; i < 10; i++) { // Compliant
print("Loop");
break myLabel;
}
