public class Customer {
private String fName;
private String lName;
private static int count;
public customer (String first, String last) {fName = first, lName = last;
++count;}
static { count = 0; }
public static int getCount() {return count; }
}
public class App {
public static void main (String [] args) {
Customer c1 = new Customer("Larry", "Smith");
Customer c2 = new Customer("Pedro", "Gonzales");
Customer c3 = new Customer("Penny", "Jones");
Customer c4 = new Customer("Lars", "Svenson");
c4 = null;
c3 = c2;
System.out.println (Customer.getCount());
}

Given:
class CheckClass {
public static int checkValue (String s1, String s2) {
return s1 length() - s2.length();
}
}
and the code fragment:
String[] strArray = new String [] {"Tiger", "Rat", "Cat", "Lion"}
//line n1
for (String s : strArray) {
System.out.print (s + " ");
}
Which code fragment should be inserted at line n1 to enable the code to print Rat Cat Lion Tiger?

• A. Arrays.sort(strArray, (CheckClass : : new) : : checkValue);
• B. Arrays.sort(strArray, (CheckClass : : new).checkValue);
• C. Arrays.sort(strArray, CheckClass : : new : : checkValue);
• D. Arrays.sort(strArray, CheckClass : : checkValue);

Given:
public final class IceCream {
public void prepare() {}
}
public class Cake {
public final void bake(int min, int temp) {}
public void mix() {}
}
public class Shop {
private Cake c = new Cake ();
private final double discount = 0.25;
public void makeReady () { c.bake(10, 120); }
}
public class Bread extends Cake {
public void bake(int minutes, int temperature) {}
public void addToppings() {}
}
Which statement is true?

• A. All classes compile successfully.
• B. A compilation error occurs in Cake.
• C. A compilation error occurs in IceCream.
• D. A compilation error occurs in Bread
• E. A compilation error occurs in Shop.

Given:
Message.properties:
msg = Welcome!
Message_fr_FR.properties:
msg = Bienvenue!
Given the code fragment:
// line n1
Locale.setDefault(locale);
ResourceBundle bundle = ResourceBundle.getBundle("Message");
System.out.print(bundle.getString("msg"));
Which two code fragments, when inserted at line n1 independently, enable to print Bienvenue!?

• A. Locale locale = new Locale ("fr", "FR");
• B. Locale locale = Locale.FRANCE;
• C. Locale locale = new Locale("fr-FR");
• D. Locale locale = new Locale ("FRANCE", "FRENCH");
• E. Locale locale = Locale.forLanguageTag("fr");

Given that /green.txt and /colors/yellow.txt are accessible, and the code fragment:
Path source = Paths.get("/green.txt);
Path target = Paths.get("/colors/yellow.txt);
Files.move(source, target, StandardCopyOption.ATOMIC_MOVE);
Files.delete(source);
Which statement is true?

• A. The yellow.txt file content is replaced by the green.txt file content and an exception is thrown.
• B. The file green.txt is moved to the /colors directory.
• C. The green.txt file content is replaced by the yellow.txt file content and the yellow.txt file is deleted.
• D. A FileAlreadyExistsException is thrown at runtime.
