``++private++`` or ``++internal++`` types or ``++private++`` members that are never executed or referenced are dead code: unnecessary, inoperative code that should be removed. Cleaning out dead code decreases the size of the maintained codebase, making it easier to understand the program and preventing bugs from being introduced.

|
|
{
|
|
private void UnusedPrivateMethod() {...} // Noncompliant
|
|
|
|
private class UnusedClass {...} // Noncompliant
|
|
}
