Description
This method is never called or is only called from other dead code.
Risk Factors
TBD
Examples
Example 1
In the following class, the method doWork() can never be called.
public class Dead {
private void doWork() {
System.out.println("doing work");
}
public static void main(String[] args) {
System.out.println("running Dead");
}
}
Example 2
In the following class, two private methods call each other, but since neither one is ever invoked from anywhere else, they are both dead code.
public class DoubleDead {
private void doTweedledee() {
doTweedledumb();
}
private void doTweedledumb() {
doTweedledee();
}
public static void main(String[] args) {
System.out.println("running DoubleDead");
}
}
(In this case it is a good thing that the methods are dead: invoking either one would cause an infinite loop.)
