Filter cannot be resolved to a type??

[Harrie_KalaChakra]

I had error showed with this code
@ line I declared class AgeFilter, there's error:
"Filter cannot be resolved to a type"

private static class AgeFilter implements Filter {
/**
* Accept child rows when age > 50.
*
* @param child The child ResultSet.
* @return true, if age > 50.
*
*/
public boolean evaluate( ResultSet child )
{
try {
ResultSet cursor = (ResultSet) child;
int age = cursor.getInt( "Employee.age" );
return age > 50;
} catch( ULjException exc ) {
Demo.displayException( exc );
return false;
}
}
}

I m newbie in JAVA, so I didn't understand why that error keep showed??

What should I do to get out from this error?? Any suggestion for me??

Any help would be appreciated

You need to import the Filter interface that you are trying to implement.
