Given the code fragment:
Path file = Paths.get ("courses.txt");
// line n1
Assume the courses.txt is accessible.
Which code fragment can be inserted at line n1 to enable the code to print the content of the courses.txt file?

Given:

and the code fragment:

What is the result?
true

Given:
public final class IceCream {
public void prepare() {}
}
public class Cake {
public final void bake(int min, int temp) {}
public void mix() {}
}
public class Shop {
private Cake c = new Cake ();
private final double discount = 0.25;
public void makeReady () { c.bake(10, 120); }
}
public class Bread extends Cake {
public void bake(int minutes, int temperature) {}
public void addToppings() {}
}
Which statement is true?

Given the code fragment:
public class Foo {
public static void main (String [ ] args) {
Map<Integer, String> unsortMap = new HashMap<> ( );
unsortMap.put (10, "z");
unsortMap.put (5, "b");
unsortMap.put (1, "d");
unsortMap.put (7, "e");
unsortMap.put (50, "j");
Map<Integer, String> treeMap = new TreeMap <Integer, String> (new
Comparator<Integer> ( ) {
@ Override public int compare (Integer o1, Integer o2) {return o2.compareTo (o1); } } ); treeMap.putAll (unsortMap); for (Map.Entry<Integer, String> entry : treeMap.entrySet () ) { System.out.print (entry.getValue () + " ");
}
}
}
What is the result?

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.ready()) { //line n1
isr.skip(2);
i = isr.read ();
c = (char) i;
System.out.print(c);
}
} catch (Exception e) {
e.printStackTrace();
}
}
What is the result?
