Question
Collections can be broken down into two types linear and sequential linear and nonlinear hierarchical and sequential Arrays and Array Lists All arrays are objects of the base type _____ class. Super Array Object Base Given an array declared to hold 100 values, the largest index that can be used with the array is: 101 99 100 undetermined If an array named num is dimensioned to hold 10 values, how would you store 11 in the 3rd physical location? num[3] = 11; num[2] = 11; num = 50[4] num3 = 11; int [] anArray = {86, 66, 76, 92, 95, 88}; for (int i = anArray.Length-1; i > -1; i--) {total += anArray[i];} Using the declaration above for an Array, what is added to total during the first iteration? 0 86, 66, 76, 92 and 95 88 unknown, because i is not initialized Which of the following could be a method heading for a member method that returns an array? int [] void DoSomething() int [] DoSomething() void int [] DoSomething() void DoSomething[] If an array is to be sent to a method, which of the following is a valid heading for a method? void DisplayOutput(double [] anArray) void DisplayOutput(double anArray) void DisplayOutput(double [10] anArray) void DisplayOutput(double anArray [10]) Which of the following is a valid example of calling a method and sending it an array argument? DisplayArrayContents(int [] anArray); DisplayArrayContents(anArray[10]); DisplayArrayContents(anArray); DisplayArrayContents(int [10] anArray); If you do not know the size of the array needed, you can create an array large enough to hold any entries and tell users to enter a predetermined sentinel value after they enter the last value. Using this approach: requires that you increment a counter as values are entered so that you know how many elements are stored in your array is preferred to defining a static sized array. requires that you dimension the array to hold at least 100 entries. requires the array be defined to hold string elements.Explanation / Answer
Hi, I have answered first 5 questions.
Please repost others on separate post.
Please let me know in case of any issue in first 5.
Q1.
Collection can be divided into two parts:
linear and non-linear
List is linear collection
Set, Map are non-linear
Q2.
Ans: a. Object
Object class is the baase class of all other classes in Java
Q3.
Ans: b. 99
Array index starts from 0 to n-1, n is the size of an array
Q4. Ans: b. num[2] = 11
index of third element is (3-1) = 2
Q5.
Ans: b. 88
Loop starts from i = anArray.length-1 = 5, and anArray[5] = 88
