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

    Sam John Jim

  • B

    John Jim

  • C

    A compilation error occurs at line n1.

  • D
