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?

• A.A NullPointerException is thrown as runtime.
• B.The program executes successfully and the STUDENT table is NOT updated with any record.
• C.A SQLException is thrown as runtime.
• D.The program executes successfully and the STUDENT table is updated with one record.

Given the definition of the Emp class:
public class Emp
private String eName;
private Integer eAge;
Emp(String eN, Integer eA) {
this.eName = eN;
this.eAge = eA;
}
public Integer getEAge () {return eAge;}
public String getEName () {return eName;}
}
and code fragment:
List<Emp>li = Arrays.asList(new Emp("Sam", 20), New Emp("John", 60), New Emp ("Jim", 51)); Predicate<Emp> agVal = s -> s.getEAge() > 50; //line n1 li = li.stream().filter(agVal).collect(Collectors.toList()); Stream<String> names = li.stream()map.(Emp::getEName); //line n2 names.forEach(n -> System.out.print(n + " ")); What is the result?

• A.A compilation error occurs at line n1.
• B.John Jim
