Given:
class FuelNotAvailException extends Exception { }
class Vehicle {
void ride() throws FuelNotAvailException {//line n1
System.out.println("Happy Journey!");
}
}
class SolarVehicle extends Vehicle {
public void ride () throws Exception {//line n2
super ride ();
}
}
and the code fragment:
public static void main (String[] args) throws FuelNotAvailException, Exception {
Vehicle v = new SolarVehicle ();
v.ride();
}
Which modification enables the code fragment to print Happy Journey!?

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
Which statement is true?

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.getString(1));
16.System.out.println("Description:" + rs.getString(2));
17.System.out.println("Price:" + rs.getString(3));
18. System.out.println(Quantity:" + rs.getString(4));
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:
public static void main (String [ ] args) throws IOException {
BufferedReader br = new BufferedReader (new InputStremReader (System.in)); System.out.print ("Enter GDP: ");
//line 1
}
Which code fragment, when inserted at line 1, enables the code to read the GDP from the user?
