Given:
public interface Moveable<Integer> {
public default void walk (Integer distance) {System.out.println("Walking");)
public void run(Integer distance);
}
Which statement is true?

• A.Moveable can be used as below:
  Moveable animal = (Integer n) - > System.out.println(n);
  animal.run(100);
  Moveable.walk(20);
• B.Moveable can be used as below:
  Moveable<Integer> animal = n - > System.out.println("Running" + n);
  animal.run(100);
  animal.walk(20);
• C.Movable cannot be used in a lambda expression.
• D.Moveable can be used as below:
  Moveable<Integer> animal = n - > n + 10;
  animal.run(100);
  animal.walk(20);

public static <T> Foo<T, T> twice (T value) (return new Foo<T, T> (value, value); ) public K getKey () (return key;) public V getValue () (return value;)
}
Which option fails?

• A.Foo<String, String> pair = Foo.<String>twice ("Hello World!");
• B.Foo<String, Integer> mark = new Foo<String, Integer> ("Steve", 100);
• C.Foo<?, ?> percentage = new Foo <> (97, 32);
• D.Foo<String, String> grade = new Foo <> ("John", "A");

Given the definition of the Empclass:
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.John Jim
• B.Sam John Jim
• C.A compilation error occurs at line n2.
• D.A compilation error occurs at line n1.
