문제 #1

Given:
final class Folder {//line n1
//line n2
public void open () {
System.out.print("Open");
}
}
public class Test {
public static void main (String [] args) throws Exception {
try (Folder f = new Folder()) {
f.open();
}
}
}
Which two modifications enable the code to print Open Close? (Choose two.)

A. At line n2, insert:public void close () throws IOException {System.out.print("Close");}
B. Replace line n1 with:class Folder extends Closeable {
C. Replace line n1 with:class Folder extends Exception {
D. Replace line n1 with:class Folder implements AutoCloseable {
E. At line n2, insert:final void close () {System.out.print("Close");}

문제 #2

Given the code fragment:
List<String> codes = Arrays.asList ("DOC", "MPEG", "JPEG");
codes.forEach (c -> System.out.print(c + " "));
String fmt = codes.stream()
.filter (s-> s.contains ("PEG"))
.reduce((s, t) -> s + t).get();
System.out.println("\n" + fmt);
What is the result?

A. The order of the output is unpredictable.
B. MPEGJPEGMPEGJPEG
C. DOC MPEG MPEGJPEGMPEGMPEGJPEG
D. DOC MPEG JPEGMPEGJPEG

문제 #3

Given the code fragment:
LocalDate valentinesDay =LocalDate.of(2015, Month.FEBRUARY, 14);
LocalDate nextYear = valentinesDay.plusYears(1);
nextYear.plusDays(15); //line n1
System.out.println(nextYear);
What is the result?

A. A compilation error occurs at line n1.
B. 2016-02-29
C. 2016-02-14
D. A DateTimeException is thrown.

문제 #4

문제 #5

Given:
class Student {
String course, name, city;
public Student (String name, String course, String city) {
this.course = course; this.name = name; this.city = city;
}
public String toString() {
return course + ":" + name + ":" + city;
}
public String getCourse() {return course;}
public String getName() {return name;}
public String getCity() {return city;}
and the code fragment:
List<Student> stds = Arrays.asList(
new Student ("Jessy", "Java ME", "Chicago"),
new Student ("Helen", "Java EE", "Houston"),
new Student ("Mark", "Java ME", "Chicago"));
stds.stream()
.collect(Collectors.groupingBy(Student::getCourse))
.forEach(src, res) -> System.out.println(scr));
What is the result?

A. A compilation error occurs.
B. [Java ME: Jessy:Chicago, Java ME: Mark:Chicago][Java EE: Helen:Houston]
C. [Java EE: Helen:Houston][Java ME: Jessy:Chicago, Java ME: Mark:Chicago]
