Given the code fragment:
dataFormat df;
Which statement defines a new DataFormat object that displays the default date format for the UK Locale?

• A.  df = new DateFormat.getDateInstance (DateFormat.DEFAULT, Locale(UK));
• B.  df = DateFormat.getDateInstance (DateFormat.DEFAULT, UK);
• C.  df = DateFormat.getDateInstance (DateFormat.DEFAULT, Locale(UK));
• D.  df = DateFormat.getDateInstance (DateFormat.DEFAULT, Locale.UK);
• E.  df = new DateFormat.getDataInstance (DataFormat.DEFAULT, Locale.UK);

Given the code fragment:
try {
String query = "SELECT * FROM Employee WHERE ID=110";
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(query); // Line 13
System.out.println("Employee ID: " + rs.getInt("ID")); // Line 14
} catch (Exception se) {
System.out.println("Error");
}
Assume that the SQL query matches one record. What is the result of compiling and executing this code?

• A.  Compilation fails due to an error at line 14.
• B.  The code prints the employee ID.
• C.  Compilation fails due to an error at line 13.
• D.  The code prints error.

Given the code fragment:
public static void processFile () throws IOException { Try (FileReader fr = new FileReader ("logfilesrc.txt");
FileWriter fw = new FileWriter ("logfilesdst.txt") ) {
int i = fr.read();
}
}
Which statement is true?

• A.  The java runtime automatically closes the FileWriter Instance first and the FileReader instance next.
• B.  The code fragment contains compilation errors.
• C.  The java runtime automatically closes the FileReader Instance first and the FileWriter instance next.
• D.  The developer needs to close the FileReader instance first and the FileWriter instance explicitly in a catch block.
• E.  The Java runtime may close the FileReader and FileWriter instance in an intermediate manner. Developers should not rely on the order in which they are closed.

Given the code fragment: SimpleDateFormat sdf = new SimpleDateFormat("zzzz", Locale.US);

Which statement creates a low-overhead, low contention random number generator that is isolated to a thread to generate a random number between 1 and 100?

• A.  int i = (int) Math.random()*.nextInt(1, 101);
• B.  int i = ThreadLocalRandom.current().nextInt (1, 101);
• C.  int i = ThreadSaferandom.current().nextInt(1, 101);
• D.  int i = (int) Match.random (1, 101);
• E.  int i = new Random (). nextInt (100)+1;
