Given records from the Player table:
and given the code fragment:
try {
Connection conn = DriverManager.getConnection(URL, username, password);
Statement st= conn.createStatement(
ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
st.execute (“SELECT * FROM Player”);
st.setMaxRows(2);
ResultSet rs = st.getResultSet();
rs.absolute(3);
while (rs.next ()) {
System.out.println(rs.getInt(1) + “ “ + rs.getString(2));
}
} catch (SQLException ex) {
System.out.print(“SQLException is thrown.”);
}
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with URL, username, and password.
The SQL query is valid.
What is the result?
Given the Greetings.properties file, containing:
and given:
What is the result?
Given:
class Student {
String course, name, city;
public Student (String name, String course, String city) {
this.course = course; this.name = name; this.city = city;
}
public String toString() {
return course + “:” + name + “:” + city;
}
public String getCourse() {return course;}
public String getName() {return name;}
public String getCity() {return city;}
and the code fragment:
List < Student > stds = Arrays.asList(
new Student (“Jessy”, “Java ME”, “Chicago”),
new Student (“Helen”, “Java EE”, “Houston”),
new Student (“Mark”, “Java ME”, “Chicago”));
stds.stream()
.collect(Collectors.groupingBy(Student::getCourse))
.forEach(src, res) - > System.out.println(res));
What is the result?
Given:
public class Counter {
public static void main (String[ ] args) {
int a = 10;

assert (b > =1) : “Invalid Denominator”;
int с = a / b;
System.out.println (c);
}
}

Given:
and the code fragment:
What is the result?
Given the code fragments:
class MyThread implements Runnable {
private static AtomicInteger count = new AtomicInteger (0);
public void run () {
int x = count.incrementAndGet();
System.out.print (x+” “);
}
}
and
Thread thread1 = new Thread(new MyThread());
Thread thread2 = new Thread(new MyThread());
Thread thread3 = new Thread(new MyThread());
Thread [] ta = {thread1, thread2, thread3};
for (int x= 0; x < 3; x++) {
ta[x].start();
}
Which statement is true?
Given the code fragment:
Which two code fragments, when inserted at line n1 independently, result in the output PEEK: Unix?
Given the code fragment:
List < Integer > values = Arrays.asList (1, 2, 3);
