KoKo created NETBEANS-4680:
------------------------------
Summary: No code completion in Stream#map() function's lambda
expression body unless there is a return statement already
Key: NETBEANS-4680
URL: https://issues.apache.org/jira/browse/NETBEANS-4680
Project: NetBeans
Issue Type: Improvement
Components: java - Hints
Reporter: KoKo
For the given code:
{code:java}
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
public class Test {
static class Student {
private Integer id;
private Integer age;
private String gender;
private String firstName;
private String lastName;
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}
