Given:
Item table
• ID, INTEGER: PK
• DESCRIP, VARCHAR(100)
• PRICE, REAL
• QUANTITY< INTEGER
And given the code fragment:
9. try {
10.Connection conn = DriveManager.getConnection(dbURL, username, password);
11. String query = “Select * FROM Item WHERE ID = 110”;
12. Statement stmt = conn.createStatement();
13. ResultSet rs = stmt.executeQuery(query);
14.while(rs.next()) {
15.System.out.println(“ID:“ + rs.getInt(“Id”));
16.System.out.println(“Description:“ + rs.getString(“Descrip”));
17.System.out.println(“Price:“ + rs.getDouble(“Price”));
18. System.out.println(Quantity:“ + rs.getInt(“Quantity”));
19.}
20. } catch (SQLException se) {
21. System.out.println(“Error”);
22. }
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with the dbURL, userName, and passWord exists.
The SQL query is valid.
What is the result?
Given the code fragment:
List
System.out.println (
// line n1
);
Which code fragment, when inserted at line n1, enables the code to print the count of string elements whose length is greater than three?
Given that course.txt is accessible and contains:
Course : : Java
and given the code fragment:
public static void main (String[ ] args) {
int i;
char c;
try (FileInputStream fis = new FileInputStream (“course.txt”);
InputStreamReader isr = new InputStreamReader(fis);) {
while (isr.ready()) { //line n1
isr.skip(2);
i = isr.read ();
c = (char) i;
System.out.print(c);
}
} catch (Exception e) {
e.printStackTrace();
}
}
What is the result?
