Given the code fragments:
and
Which two modifications enable to sort the elements of the emps list? (Choose two.)
Given that course.txt is accessible and contains:
Course : : Java
and given the code fragment:
public static void main (String[ ] args) {
int i;
char c;
try (FileInputStream fis = new FileInputStream (“course.txt”);
InputStreamReader isr = new InputStreamReader(fis);) {
while (!isr.close()) { //line n1
isr.skip(2);
i = isr.read ();
c = (char) i;
System.out.print(c);
}
} catch (Exception e) {
e.printStackTrace();
}
}
What is the result?
Given that data.txt and alldata.txt are accessible, and the code fragment:
What is required at line n1 to enable the code to overwrite alldata.txt with data.txt?
Given the definition of the Vehicle class:
Class Vehhicle {
int distance;//line n1
Vehicle (int x) {
this distance = x;
}
public void increSpeed(int time) {//line n2
int timeTravel = time;//line n3
class Car {
int value = 0;
public void speed () {
value = distance /timeTravel;
System.out.println (“Velocity with new speed”+value+”kmph”);
}
}
new Car().speed();
}
}
and this code fragment:
Vehicle v = new Vehicle (100);
v.increSpeed(60);
What is the result?

}
and the code fragment:
class Birdie {
public static void main (String [ ] args) {
fly( ( ) - > new Bird ( ));
fly (Penguin : : new);
}
/* line n1 */
}
