> private Integer id;
> private Integer age;

> public Integer getId() {
> return id;
> }
> public void setId(Integer id) {
> this.id = id;
> }
> public Integer getAge() {
> return age;
> }
> public void setAge(Integer age) {
> this.age = age;
> }
> public String getGender() {
> return gender;
> }
> public void setGender(String gender) {
> this.gender = gender;
> }
> public String getFirstName() {
> return firstName;

> public void setFirstName(String firstName) {
> this.firstName = firstName;
> }
> public String getLastName() {
> return lastName;

> public void setLastName(String lastName) {
> this.lastName = lastName;
> }
> public Student(Integer id, Integer age, String gender, String
> firstName, String lastName) {
> this.id = id;
> this.age = age;
> this.gender = gender;
> this.firstName = firstName;
> this.lastName = lastName;
> }
> }
> public static void main(String[] args) {
> Student e1 = new Student(1, 23, "M", "Rick", "Beethoven");
> Student e2 = new Student(2, 13, "F", "Martina", "Hengis");
> Student e3 = new Student(3, 43, "M", "Ricky", "Martin");
> Student e4 = new Student(4, 26, "M", "Jon", "Lowman");
> Student e5 = new Student(5, 19, "F", "Cristine", "Maria");
> List<Student> students = Arrays.asList(e1, e2, e3, e4, e5);
> students.stream()
> .map(s -> {
> s.setAge(s.getAge() + 1);
> return s;
>
> })
> .collect(Collectors.toList());
> }
> }
> {code}
> if I comment the the *return statement* in Stream#map() function, there will
> be no code completion in map function and after map function.
> {code:java}
> students.stream()
> .map(s -> {
> s.setAge(s.getAge() + 1); // no code completion for getter and
> setter here
> // return s;
>
> })
> .collect(Collectors.toList()); // no code completion here
> {code}
