ABSTRACT
This statement will never be executed.
EXPLANATION
The surrounding code makes it impossible for this statement to ever be executed.
Example: The condition for the second if statement is impossible to satisfy. It requires that the variable s be non-null, while on the only path where s can be assigned a non-null value there is a return statement.
String s = null;
if (b) {
s = "Yes";
return;
}
if (s != null) {
Dead();
}
