A. is wrong because it provides initial values for only one dimension.is wrong because it use something other than curly braces for the initialization.0 Points You want subclasses in any package to have access to members of a superclass. is wrong because it initializes an int array with String literals. may access features. protected C. not which instances. Methods and variables are collectively known as members. Method and variable members are given access control in exactly the same way.B. private makes a member accessible only from within its own class protected makes a member accessible only to classes in the same package or subclass of the class default access is very similar to protected (make sure you spot the difference) default access makes a member . public D. transient Answer Key: C Feedback: Access modifiers dictate which classes. transient indicates that a variable is not part of the persistent state of an object. when applied to a variable it makes it impossible to reinitialise a variable once it has been initialised abstract declares a method that has not been implemented. After examining the above it should be obvious that the access modifier that provides the most restrictions for . volatile indicates that a thread must reconcile its working copy of the field with the master copy every time it accesses the variable. when applied to a method it prevents a method from being overridden in a subclass.accessible only to classes in the same package. can access the member (assuming the class itself is visible) final makes it impossible to extend a class. public means that all other classes regardless of the package that they belong to.

A.synchronized public final void m1() {} 4.static final void m1(){} 3. and 5 D. if it is not explicitly declared public it will be . (1).2. and (5).boolean setFlag(Boolean [] test). 2 and 4 Answer Key: B Feedback: (2). 4. 4. 5. is incorrect because an interface method must be public. 3 and 5 C. 3. 3. (3).public void main(String [] args). These are all valid interface method signatures. A. 1 and 2 B.public static void main(String [] args).public float getVol(float x). 2. 0 Points Which option among the following creates an instance of an array? A. char[ ] ca = "Some String". Answer Key: A Feedback: int[ ] ia = new int[15]. Question 9 of 10 10. (4) is incorrect because interface methods cannot be static. float fa = new float[20]. It uses correct array declaration and correct array construction. int ia[ ] [ ] = { 4.2. int[ ] ia = new int[15].made public implicitly. { 1.3 }. C. is correct. 5. 6 }. B. D. . 5. int ia[ ] [ ] = { 4. is wrong.3 }. but it is supplied with a primitive type in the declaration. whereas your intention was to create a 3 x 3 two-dimensional array.0 Points Which of the following class level (nonlocal) variable declarations will not compile? . The compiler thinks that you are trying to create two arrays because there are two array initialisers to the right of the equals. Question 10 of 10 10. char[ ] ca = "Some String". 6 }. It generates a compiler error: incompatible types because the array variable declaration is not correct. It generates a compiler error: incompatible types because a string literal is not assignable to a character type variable. is incorrect.2.float fa = new float[20]. is incorrect. The array construction expects a reference type. it generates a compiler error <identifier> expected. { 1. protected int a. private synchronized int e. protected int a. will not compile. will compile because volatile is a proper variable modifier.A. will compile because protected and transient are legal variable modifiers. volatile int d. the synchronized modifier applies only to methods. C. B. . Answer Key: A Feedback: private synchronized int e. D. volatile int d. and transient int b = 3. transient int b = 3. Compares two numerals and prints the lower value Correct C.
