produces incompatible types
found : java.util.Enumeration<capture of ?>
required: java.util.Enumeration<java.lang.String>
Enumeration<String> e = p.propertyNames();

while this

compiles ok.

What is the problem?

Costs matter. Justice lies in processes not outcomes. Crime is caused by criminals.

Class Properties was from before the time that generics were added to Java. So the method propertyNames() returns a raw Enumeration, and not an Enumeration<String>.
