Given:

and the code fragment:

What is the result?

• A.2000.0
• B.A compilation error occurs.
• C.0.0
• D.1500.0

Given this code;

Which two are correct after this class is instantiated and tested?

• A.If the value of i is set to 8, the value of j could be any integer value.
• B.If the value of j is set to 5, the value of i will be 15.
• C.If the value of i remains 3, the value of j will remain 9.
• D.If the value of i is set to 5, the value of j will be 1.
• E.If the value of i is set to 6, the value of j will be 18.
• F.If the value of j is set to 15, the value of i could be any integer value.

Given that these files exist and are accessible:
/sports/info.txt
/sports/cricket/players.txt
/sports/cricket/data/ODI.txt
and given the code fragment:
int maxDepth =2;
Stream<Path> paths = Files.find(Paths.get("/sports"),
maxDepth,
(p, a) -> p.getFileName().toString().endsWith ("txt"),
FileVisitOption.FOLLOW_LINKS);
Long fCount = paths.count();
System.out.println(fCount);
Assuming that there are NO soft-link/symbolic links to any of the files in the directory structure, what is the result?

• A.2
• B.3
• C.1
• D.An Exception is thrown at runtime.

Given the records from the Employee table:

and given the code fragment:
try {
Connection conn = DriverManager.getConnection (URL, userName, passWord); Statement st = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE); st.execute("SELECT*FROM Employee"); ResultSet rs = st.getResultSet(); while (rs.next()) { if (rs.getInt(1) ==112) { rs.updateString(2, "Jack");
}
}
rs.absolute(2);
System.out.println(rs.getInt(1) + " " + rs.getString(2));
} catch (SQLException ex) {
System.out.println("Exception is raised");
}
Assume that:
The required database driver is configured in the classpath.
The appropriate database accessible with the URL, userName, and passWord exists.
What is the result?

• A.The program prints Exception is raised.
• B.The Employee table is updated with the row:112 Jackand the program prints:112 Jerry
• C.The Employee table is not updated and the program prints:112 Jerry
• D.The Employee table is updated with the row:112 Jackand the program prints:112 Jack

Given the code fragments:
public class Book implements Comparator<Book> {
String name;
double price;
public Book () {}
public Book(String name, double price) {
this.name = name;
this.price = price;
}
public int compare(Book b1, Book b2) {
return b1.name.compareTo(b2.name);
}
public String toString() {
return name + ":" + price;
}
}
and
List<Book>books = Arrays.asList (new Book ("Beginning with Java", 2), new book ("A Guide to Java Tour", 3)); Collections.sort(books, new Book()); System.out.print(books); What is the result?

• A.[Beginning with Java:2, A Guide to Java Tour:3]
• B.[A Guide to Java Tour:3.0, Beginning with Java:2.0]
• C.A compilation error occurs because the Book class does not override the abstract method compareTo().
• D.An Exception is thrown at run time.
