Oracle Java SE 17 Developer Sample Questions (Q10-Q15):

NEW QUESTION # 10
Given the code fragments:

Which action prints Wagon : 200?

  • A. At line n1, implement the java.io, Serializable interface.
  • B. At line n2, in the main method signature, add throws IoException, ClassNotFoundException.
  • C. At line n3, replace readObject (0 with readLine().
  • D. At line n2, in the main method signature, add throws IOException, ClassCastException.
  • E. At Line n3, replace Car with LuxurayCar.
  • F. At Line n1, implement the java.io.AutoCloseable interface

Answer: B

Explanation:
The code fragment is trying to read an object from a file using the ObjectInputStream class. This class throws an IOException and a ClassNotFoundException. To handle these exceptions, the main method signature should declare that it throws these exceptions. Otherwise, the code will not compile. If the main method throws these exceptions, the code will print Wagon : 200, which is the result of calling the toString method of the LuxuryCar object that was written to the file.

NEW QUESTION # 11
Given:

  • A. Hello
  • B. Compilation fails
  • C. there
  • D. A NumberFormatException is thrown

Answer: B

Explanation:
The code fragment will fail to compile because the parseInt method of the Integer class is a static method, which means that it can be invoked without creating an object of the class. However, the code is trying to invoke the parseInt method on an object of type Integer, which is not allowed. The correct way to invoke the parseInt method is by using the class name, such as Integer.parseInt (s). Therefore, the code fragment will produce a compilation error. Reference: Integer (Java SE 17 & JDK 17) - Oracle


NEW QUESTION # 12
Daylight Saving Time (DST) is the practice of advancing clocks at the start of spring by one hour and adjusting them backward by one hour in autumn.
Considering that in 2021, DST in Chicago (Illinois) ended on November 7th at 2 AM, and given the fragment:

What is the output?

  • A. False
    false
  • B. false
    true
  • C. true
    true
  • D. true
    false

Answer: D

Explanation:
The answer is A because the code fragment uses the ZoneId and ZonedDateTime classes to create two date-time objects with the same local date-time but different zone offsets. The ZoneId class represents a time-zone ID, such as America/Chicago, and the ZonedDateTime class represents a date-time with a time-zone in the ISO-8601 calendar system. The code fragment creates two ZonedDateTime objects with the same local date-time of 2021-11-07T01:30, but different zone IDs of America/Chicago and UTC. The code fragment then compares the two objects using the equals and isEqual methods.
The equals method compares the state of two objects for equality. In this case, it compares the local date-time, zone offset, and zone ID of the two ZonedDateTime objects. Since the zone offsets and zone IDs are different, the equals method returns false.
The isEqual method compares the instant of two temporal objects for equality. In this case, it compares the instant of the two ZonedDateTime objects, which is derived from the local date-time and zone offset. Since DST in Chicago ended on November 7th at 2 AM in 2021, the local date-time of 2021-11-07T01:30 in America/Chicago corresponds to the same instant as 2021-11-07T06:30 in UTC. Therefore, the isEqual method returns true.
Hence, the output is true false. Reference:

NEW QUESTION # 13
Which statement is true about modules?

  • A. Automatic and named modules are on the module path.
  • B. Only automatic modules are on the module path.
  • C. Automatic and unnamed modules are on the module path.
  • D. Only unnamed modules are on the module path.
  • E. Only named modules are on the module path.

Answer: A

Explanation:
A module path is a sequence of directories that contain modules or JAR files. A named module is a module that has a name and a module descriptor (module-info.class) that declares its dependencies and exports. An automatic module is a module that does not have a module descriptor, but is derived from the name and contents of a JAR file. Both named and automatic modules can be placed on the module path, and they can be resolved by the Java runtime. An unnamed module is a special module that contains all the classes that are not in any other module, such as those on the class path. An unnamed module is not on the module path, but it can read all other modules.


NEW QUESTION # 14
Given:

What is the result?

  • A. Nothing is printed because of an indefinite loop.
  • B. A runtime exception is thrown.
  • C. 0
  • D. Compilation fails.
  • E. 1
  • F. 2
  • G. 3
  • H. 4

Answer: D

Explanation:
The code will not compile because the variable 'x' is declared as final and then it is being modified in the switch statement. This is not allowed in Java. A final variable is a variable whose value cannot be changed once it is initialized1. The switch statement tries to assign different values to 'x' depending on the value of 'y', which violates the final modifier. The compiler will report an error: The final local variable x cannot be assigned. It must be blank and not using a compound assignment.
