Given the code fragments:
class TechName {
String techName;
TechName (String techName) {
this.techName=techName;
}
}
and
List<TechName> tech = Arrays.asList (
new TechName("Java-"),
new TechName("Oracle DB-"),
new TechName("J2EE-")
);
Stream<TechName> stre = tech.stream();
//line n1
Which should be inserted at line n1 to print Java-Oracle DB-J2EE-?

• A.stre.forEach(System.out::print);
• B.stre.map(a-> a.techName).forEach(System.out::print);
• C.stre.map(a-> a).forEachOrdered(System.out::print);
• D.stre.forEachOrdered(System.out::print);

Given the code fragment:
9. Connection conn = DriveManager.getConnection(dbURL, userName, passWord);
10. String query = "SELECT id FROM Employee";
11. try (Statement stmt = conn.createStatement()) {
12. ResultSet rs = stmt.executeQuery(query);
13. stmt.executeQuery("SELECT id FROM Customer");
14. while (rs.next()) {
15. //process the results
16. System.out.println("Employee ID: "+ rs.getInt("id"));
17. }
18. } catch (Exception e) {
19. System.out.println ("Error");
20. }
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with the dbURL, userName, and passWord exists.
The Employee and Customer tables are available and each table has id column with a few records and the SQL queries are valid.
What is the result of compiling and executing this code fragment?

• A.The program prints Error.
• B.The program prints employee IDs.
• C.The program prints customer IDs.
• D.compilation fails on line 13.
