Given the structure of the STUDENT table:
Student (id INTEGER, name VARCHAR)
Given:
public class Test {
static Connection newConnection =null;
public static Connection get DBConnection () throws SQLException {
try (Connection con = DriveManager.getConnection(URL, username, password)) { newConnection = con;
}
return newConnection;
}
public static void main (String [] args) throws SQLException {
get DBConnection ();
Statement st = newConnection.createStatement();
st.executeUpdate("INSERT INTO student VALUES (102, 'Kelvin')");
}
}
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with the URL, userName, and passWord exists.
The SQL query is valid.
What is the result?

Given:
class ImageScanner implements AutoCloseable {
public void close () throws Exception {
System.out.print ("Scanner closed.");
}
public void scanImage () throws Exception {
System.out.print ("Scan.");
throw new Exception("Unable to scan.");
}
}
class ImagePrinter implements AutoCloseable {
public void close () throws Exception {
System.out.print ("Printer closed.");
}
public void printImage () {System.out.print("Print."); }
}
and this code fragment:
try (ImageScanner ir = new ImageScanner();
ImagePrinter iw = new ImagePrinter()) {
ir.scanImage();
iw.printImage();
} catch (Exception e) {
System.out.print(e.getMessage());
}
What is the result?

Which statement is true about the single abstract method of the java.util.function.Function interface?

Given the code fragment:
ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 3, 0, 0, 0, ZoneID.of("UTC-
7"));
ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of("UTC-
5"));
long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1
System.out.println("Travel time is" + hrs + "hours");
What is the result?

Given the code fragment:

Assume that the URL, username, and password are valid.
