Exam 9: Arrays

Which method would you most likely use to find the location of an element in the vector?

Given the following method heading public static void mystery(int list[], int size)and the declarationint[] alpha = new int[75];Which of the following is a valid call to the method mystery?

The base address of an array is the memory location of the first array component.

You can create an array of reference variables to manipulate objects.

double[] as = new double[7]; Double[] bs;bs = as;How many objects are present after the code fragment in the accompanying figure is executed?

In which package is the class Vector located?

A Vector object can shrink during program execution.

Which method of the class vector would you use to remove an element at a specific location?

Given the method heading public static void strange(int a, int b)and the declarationint[] alpha = new int[20]; Int[] beta = new int[25];Which of the following is a valid call to the method strange?

char[][] table = new char[10][5];How many rows are in the array seen in the accompanying figure?

The statementint[] list = new int[15];creates list to be an array of 14 components because array index starts at 0.

Which of the following is the array subscripting operator in Java?

char[][] table = new char[10][5];What is the value of table[2].length?

When a boolean array object is instantiated, its components are initialized to false.

Arrays have a fixed number of elements.

What does the following statement do? Vector thisVector = new Vector();

Java stores two-dimensional arrays in a row order form in computer memory.

In a method call statement, when passing an array as an actual parameter, you use only its name.

Given the declarationdouble[] numList = new double[20];the statementnumList[12] = numList[5] + numList[7];updates the content of the thirteenth component of the array numList.

Consider the following method definition.public static int strange(int[] list, int listSize, int item) { Int count = 0; For (int j = 0; j < listSize; j++) (list[j]; == item) Count++; Return count; } Which of the following statements best describe the behavior of this method?
