Consider the following statement, which is intended to create an ArrayList named a to store only elements of type Thing. Assume that the Thing class has been properly defined and includes a no-parameter constructor. ArrayList a = /* missing code */;
Which of the following can be used to replace /* missing code */ so that the statement works as intended?
a. new Thing().
b. new ArrayList().
c. new ArrayList(Thing).
d. new ArrayList().
e. new ArrayList<>(Thing).
2. Consider the following statement, which is intended to create an ArrayList named numbers that can be used to store Integer values. ArrayList numbers = /* missing code */;Which of the following can be used to replace /* missing code */ so that the statement works as intended?new ArrayList()new ArrayListnew ArrayList()A. III only.
B. I and II only. C. I and III only. D. II and III only. E. I, II, and III.3. Consider the following statement, which is intended to create an ArrayList named arrList to store elements only of type String./* missing code */ = new ArrayList();Which of the following can be used to replace /* missing code */ so that the statement works as intended?A. ArrayList arrList().B. ArrayList arrList.
C. ArrayList<> arrList.
D. ArrayList arrList.
E. ArrayList arrList.4. Consider the following code segment. ArrayList nums = new ArrayList<>();nums. add(3);nums. add(2);nums. add(1);nums. add(0);nums. add(0, 4);nums. set(3, 2);nums. remove(3);nums. add(2, 0);Which of the following represents the contents of nums after the code segment has been executed?A. [2, 4, 3, 2, 0].B. [3, 2, 0, 1, 0].C. [4, 2, 0, 2, 0].D. [4, 3, 0, 2, 0].E. [4, 3, 0, 3, 0].5. Consider the following code segment. ArrayList syllables = new ArrayList();syllables. add("LA");syllables. add(0, "DI");syllables. set(1, "TU");syllables. add("DA");syllables. add(2, syllables. get(0));syllables. remove(1);System. out. println(syllables. toString());What is printed as a result of executing the code segment?A. [DI, DA, DI].
B. [DI, DI, DA].C. [LA, LA, DA].
D. [TU, DI, DA].E. [TU, TU, DA].6. Consider the following code segment. ArrayList vals = new ArrayList();vals. add(vals. size(), vals. size());vals. add(vals. size() - 1, vals. size() + 1);vals. add(vals. size() - 2, vals. size() + 2);System. out. println(vals. toString());What is printed as a result of executing the code segment?A. [0, 1, 2].B. [0, 2, 4].C. [1, 2, 3].D. [2, 1, 0].E. [4, 2, 0].
