Unused label should be removed

• UNUSED_LABEL
• Code Quality
• Low
• No tags

This rule applies when labels are declared but not used.

For maintainability, it is recommended to remove unused code. Also, it might be a mistake that a programmer forgets to use the declared label.

Noncompliant Code Example

outmost: { // UNUSED_LABEL alarm
    while (true) {
        if (finishNow) break;
        else if (updateLastAndFinish) break;
        updateState();
    }
    updateLast();
}

Compliant Code Example

outmost: {
    while (true) {
        if (finishNow) break outmost;
        else if (updateLastAndFinish) break;
        updateState();
    }
    updateLast();
}
