Using a variable name that clashes with the package name triggers the
UnnecessaryFullyQualifiedName rule because of implicit import * for package classes.
Affects PMD Version:
6.16
Rule:
UnnecessaryFullyQualifiedName
Description:
Usage of attribute length for variable threads triggers the UnnecessaryFullyQualifiedName rule.
Code Sample demonstrating the issue:
package threads;
public enum FQNTest {
;
public static void main(String[] args) {
Thread[] threads = new Thread[5];
for (int i = 0; i < threads.length; i++) {
threads[i] = new Thread(new Runnable() {
@Override
public void run() {
for (int j = 0; j < 10_000; j++) {
try {
Thread.sleep(1);
} catch (InterruptedException e) {
System.err.println(e);
}
}
}
}, "thread-" + i);
threads[i].start();
}
try {
for (Thread thread: threads) {
thread.join();
}
} catch (InterruptedException ex) {
System.err.println(ex);
}
System.out.println("[" + Thread.currentThread().getName()
+ "] All threads have finished.");
}
}
