Certification Practice
The following question is the kind of thing you could expect to be asked on a Java programming 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
}
}
The NameDirectory class must be able to hold 20 different names. What statement should replace // answer goes here for the class to function correctly?
- names[nameCount] = newName;
- names[nameCount] == newName;
- names[nameCount++] = newName;
- names[++nameCount] = newName;
The answer is available on the book’s website at http://www.java21days.com. Visit the Day 19 page and click the Certification Practice link.
