Question 142
Given:
public class Test<T> {
private T t;
public T get () {
return t;
}
public void set (T t) {
this.t = t;
}
public static void main (String args [ ] ) {
Test<String> type = new Test<>();
Test type 1 = new Test (); //line n1
type.set("Java");
type1.set(100); //line n2
System.out.print(type.get() + " " + type1.get());
}
}

Question 143
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.
