3. Primitive datatype or object
4. Method

2. The ... access modifier indicates that the variable or method can be accessed within

1. public
2. private
3. protected
4. static

3. The method that has the same class name and has no return value is called

1. constructor
2. implementor
3. method with no return value
4. package

4. Usually, the (a) method has a return value while the ..(b). Method takes

1. (a)getter ,(b) setter
2. (a)setter , (b) getter
3. (a) setter , (b) toString
4. None

5. The .(a). Is used to find an element in unsorted array while the .(b).. is used in sorted array

1. (a) Binary search , (b) Sequential search
2. (a) selection search , (b) Sequential search
3. (a) Sequential search , (b) Binary search
4. (a) selection search , (b) Binary search

6. The . Keyword indicates that only one copy of the class variable will be used for

1. static
2. private
3. protected
4. public

7. The following code is used to swap the elements at the indexes . of the array

Student temp = A[maxLoc];

A[maxLoc] = A[lastPlace];

A[lastPlace] = temp

1. Student and temp
2. maxLoc and lastPlace
3. maxLoc and temp

8. The is used to store an array of un-known size to dynamically increase/shrink

1. ArrayList
2. Cart array
3. Collections
4. String array

9. The . Java built-in class can be used to sort an arrayList using its method sort.

1. ArrayList
2. Cary array
3. String array
4. Collections

10. The method .. in the ArrayList class can be used to insert an element either to the a specific location/index.

1. contains
2. add
3. remove
4. get

11. .. appears when trying to access an array's element that its position is negative or greater than or equals to the array's length.

1. User-defined exceptions
2. Built-in Exception
3. ArraysIndexOutOfBoundsException
4. NegativeArraySizeException

12. The value of ( first , last and mid ) to find (9) in the following list using binary search:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

1. first = 5 , last = 9 , mid = 7
2. first = 8 , last = 9 , mid = 8
3. first = 5 , last = 9 , mid = 7
4. first = 0 , last = 9 , mid = 4

13. The appropriate statement to retrieve the second row length of a two-dimensional array ( arr) is:

1. arr.length
2. arr[1].length
3. arr[0].length
4. arr[2].length

14. Which sentence is accurate for the following array?

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

1. The array has one row.
2. The array has three rows.
3. The array has three column.
4. The array's length is dynamic.

15. Array can be created by

1. new operator
2. user-defined class
3. direct contents initialization
4. all of above

16. The next step to sort the following list using selection sort is:

52, 93, 88, 73, 3, 12

1. 52, 93, 12, 73, 3, 88
2. 52, 12, 88, 73, 3, 96
3. 93, 52, 88, 73, 3, 12
4. 12, 93, 88, 73, 3, 52

17. When a variable is declared as final, it cannot be changed.

1. True
2. False

18. Linear search is more efficient than binary search.

1. True
2. False

19. The appropriate statement that will remove all elements of an arrayList (list) is

1. list.contains()
2. list.remove()
3. list.clear()
4. list.sort()

20. In . , the order of elements is required.

1. binary search
2. two-dimensional array
3. linear search
4. arrayList
