E.    Compilation fails Answer: E QUESTION 62 Given the code fragment: List<String> listVal = Arrays.asList("Joe", "Paul", "Alice", "Tom"); System.out.println ( // line n1 ); Which code fragment, when inserted at line n1, enables the code to print the count of string elements whose length is greater than three? A.    listVal.stream().filter(x -> x.length()>3).count() B.    listVal.stream().map(x -> x.length()>3).count() C.    listVal.stream().peek(x -> x.length()>3).count().get() D.    listVal.stream().filter(x -> x.length()>3).mapToInt(x -> x).count() Answer: C QUESTION 63 Which statement is true about java.util.stream.Stream? A.    A stream cannot be consumed more than once. B.    The execution mode of streams can be changed during processing. C.    Streams are intended to modify the source data. D.    A parallel stream is always faster than an equivalent sequential stream. Answer: B QUESTION 64 Given the code fragment: String str = "Java is a programming language"; ToIntFunction<String> indexVal = str: : indexOf; //line n1 int x = indexVal.applyAsInt("Java"); //line n2 System.out.println(x); What is the result?

Which code fragment can be inserted at line n1 to enable the code to print the content of the courses.txt file? A.    List<String> fc = Files.list(file); fc.stream().forEach (s - > System.out.println(s)); B.    Stream<String> fc = Files.readAllLines (file); fc.forEach (s - > System.out.println(s)); C.    List<String> fc = readAllLines(file); fc.stream().forEach (s - > System.out.println(s)); D.    Stream<String> fc = Files.lines (file); fc.forEach (s - > System.out.println(s)); Answer: B QUESTION 66 Given: Which two classes use the shape class correctly? (Choose two.) A.    Option A B.    Option B C.    Option C D.    Option D E.    Option E F.    Option F Answer: BE Explanation: When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its parent class (E). However, if it does not, then the subclass must also be declared abstract (B). Note: An abstract class is a class that is declared abstract-it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed. QUESTION 67 Given: public enum USCurrency { PENNY (1), NICKLE(5), DIME (10), QUARTER(25); private int value; public USCurrency(int value) { this.value = value; } public int getValue() {return value;} } public class Coin { public static void main (String[] args) { USCurrency usCoin =new USCurrency.DIME; System.out.println(usCoin.getValue()): } } Which two modifications enable the given code to compile? (Choose two.) A.    Nest the USCurrency enumeration declaration within the Coin class. B.    Make the USCurrency enumeration constructor private. C.    Remove the new keyword from the instantion of usCoin. D.    Make the getter method of value as a static method. E.    Add the final keyword in the declaration of value. Answer: AE QUESTION 68 Given: class Sum extends RecursiveAction { //line n1 static final int THRESHOLD_SIZE = 3; int stIndex, lstIndex; int [ ] data; public Sum (int [ ]data, int start, int end) { this.data = data; this stIndex = start; this. lstIndex = end; } protected void compute ( ) { int sum = 0; if (lstIndex ?stIndex<;= THRESHOLD_SIZE) { for (int i = stIndex; i < lstIndex; i++) { sum += data [i]; } System.out.println(sum); } else { new Sum (data, stIndex + THRESHOLD_SIZE, lstIndex).fork( ); new Sum (data, stIndex, Math.min (lstIndex, stIndex + THRESHOLD_SIZE) ).compute (); } } } and the code fragment: ForkJoinPool fjPool = new ForkJoinPool ( ); int data [ ] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} fjPool.invoke (new Sum (data, 0, data.length)); and given that the sum of all integers from 1 to 10 is 55. Which statement is true? A.    The program prints several values that total 55. B.    The program prints 55. C.    A compilation error occurs at line n1. D.    The program prints several values whose sum exceeds 55. Answer: C QUESTION 69 Given the code format: Which code fragment must be inserted at line 6 to enable the code to compile? A.    DBConfiguration f; return f; B.    Return DBConfiguration; C.    Return new DBConfiguration; D.    Retutn 0; Answer: B QUESTION 70 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?
