Certification Practice
The following question is the kind of thing you could expect to be asked on a Java pro-
gramming certification test. Answer it without looking at today's material or using the
Java compiler to test the code.
Given:
public class NameDirectory {
String[] names;
int nameCount;
public NameDirectory() {
names = new String[20];
nameCount = 0;
}
public void addName(String newName) {
if (nameCount < 20)
// answer goes here
}
}
