Question 156

Which two statements are true about the Fork/Join Framework? (Choose two.)
  • Question 157

    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?

  • Question 159

    Given:
    class Book {
    int id;
    String name;
    public Book (int id, String name) {
    this.id = id;
    this.name = name;
    }
    public boolean equals (Object obj) { //line n1
    boolean output = false;
    Book b = (Book) obj;
    if (this.name.equals(b name))}
    output = true;
    }
    return output;
    }
    }
    and the code fragment:
    Book b1 = new Book (101, "Java Programing");
    Book b2 = new Book (102, "Java Programing");
    System.out.println (b1.equals(b2)); //line n2
