Class or interface name 'identifier' conflicts with import 'identifier'
The specified class or interface conflicts with a class that has been imported. This can be caused by declaring a class or interface that is already declared in the Java API, and you are trying to import that API class or interface into your source file.
The following example illustrates this error:
import java.lang.Cloneable;
class Cloneable{ /*error Cloneable has already been
imported */
//class implementation
}
