[jira] [Created] (NETBEANS-3498) Cannot add unimplemented methods
to anonymous innerclasses
Jan Lahoda created NETBEANS-3498:
------------------------------------
Summary: Cannot add unimplemented methods to anonymous innerclasses
Key: NETBEANS-3498
URL: https://issues.apache.org/jira/browse/NETBEANS-3498
Project: NetBeans
Issue Type: Bug
Components: java - Source
Affects Versions: 11.2
Reporter: Jan Lahoda
Assignee: Jan Lahoda
Fix For: 11.3
Consider code like this:
---
public class Test2 {
public static void main(String[] args) {
Comparator<String> c = new Comparator<String>() {
};
}
}
----
There is a method missing in the anonymous class, but an attempt to add it using the error fix leads to:
---
