Correct Option: D
  1. Methods and variables

  2. class

  3. variables

  4. Methods


Correct Option: D
  1. class, if, void, long, Int, continue

  2. goto, instanceof, native, finally, default, throws

  3. try, virtual, throw, final, volatile, transient

  4. strictfp, constant, super, implements, do


Correct Option: B
Explanation:

All the words in option B are among the 49 Java keywords. Although goto reserved as a keyword in Java, goto is not used and has no function.Option A is wrong because the keyword for the primitive int starts with a lowercase i.Option C is wrong because "vi

Correct Option: D
  1. public

  2. protected

  3. private

  4. transient


Correct Option: B
Explanation:

protected makes a member accessible only to classes in the same package or subclass of the class

  1. public

  2. protected

  3. private

  4. transient


Correct Option: B
Explanation:

protected makes a member accessible only to classes in the same package or subclass of the class

  1. public

  2. abstract

  3. protected

  4. synchronized

  5. default access


Correct Option: E
Explanation:

default access is the "package oriented" access modifier.

  1. int[ ] scores = {3, 5, 7};

  2. int [ ][ ] scores = {2,7,6}, {9,3,45};

  3. String cats[ ] = {"Fluffy", "Spot", "Zeus"};

  4. boolean results[ ] = new boolean [] {true, false, true};


Correct Option: B

You want a class to have access to members of another class in the same package. Which is the most restrictive access that accomplishes this objective?

  1. public

  2. private

  3. protected

  4. default access


Correct Option: D
  1. int[ ] ia = new int[15];

  2. float fa = new float[20];

  3. char[ ] ca = "Some String";

  4. int ia[ ] [ ] = { 4, 5, 6 }, { 1,2,3 };


Correct Option: A
  1. protected int a;

  2. transient int b = 3;

  3. private synchronized int e;

  4. volatile int d;


Correct Option: C

Given a method in a protected class, what access modifier do you use to restrict access to that method to only the other members of the same class?

  1. final

  2. static

  3. private

  4. protected


Correct Option: C
Explanation:

The private access modifier limits access to members of the same class.

  1. public static short stop = 23;

  2. protected short stop = 23;

  3. transient short stop = 23;

  4. final void madness(short stop);


Correct Option: A

Suppose that you would like to create an instance of a new Map that has an iteration order that is the same as the iteration order of an existing instance of a Map. Which concrete implementation of the Map interface should be used for the new instance?

  1. TreeMap

  2. HashMap

  3. LinkedHashMap

  4. The answer depends on the implementation of the existing instance.


Correct Option: C

Which class does not override the equals() and hashCode() methods, inheriting them directly from class Object?

  1. java.lang.String

  2. java.lang.Double

  3. java.lang.StringBuffer

  4. java.lang.Character
