$1)$ What does the following statement do$?$

double$[]$ array$1=$ new double$[10]$;

A$)$ Declares array$1$ to be a reference to an array of double values

B$)$ Creates an instance of an array of $10$ double values

C$)$ Will allow valid subscripts in the range of $0-9$

D$)$ All of the above

$2)$ Given that String$[]$ str has been initialized, to get a copy of str$[0]$ with all characters converted to upper case, use the following statement:

A$)$ str$.$uppercase$()$;

B$)$ str$[0].$upperCase$()$;

C$)$ str$.$toUpperCase$()$;

D$)$ str$[0].$toUpperCase$()$;

$3)$ What will be returned from the following method?

public static float$[]$ getValue$($int x$)$

A$)$ A float value

B$)$ An array of float values

C$)$ An integer

D$)$ An array of integers

$4)$ What would be the results after the following code was executed?

int$[]$ x $=\{23,55,83,19\}$;

int$[]$ y $=\{36,78,12,24\}$;

x $=$ y;

y $=$ x;

A$)$ x$[]=\{36,78,12,24\}$ and y$[]=\{23,55,83,19\}$

B$)$ x$[]=\{36,78,12,24\}$ and y$[]=\{36,78,12,24\}$

C$)$ x$[]=\{23,55,83,19\}$ and y$[]=\{23,55,83,19\}$

D$)$ This is a compilation error.

$5)$ What will be the result of executing the following code?

int$[]$ x $=\{0,1,2,3,4,5\}$;

A$)$ An array of $6$ values ranging from $0$ through $5$ and referenced by the variable x will be created.

B$)$ A compilation error will occur.

C$)$ The program will crash when it is executed.

D$)$ The value of x$[1]$ will be $0,$ x$[2]$ will be $0,$ x$[3]$ will be $0,$ x$[4]$ will be $0,$ x$[5]$ will be $0,$ and x$[6]$ will be $0.$

$6)$ What would be the results of the following code?

int$[]$ x $=\{55,33,88,22,99,$

$11,44,66,77\}$;

int a $=10$;

if$($x$[2]>$ x$[5])$

a $=5$;

else

a $=8$;

A$)$ a $=5$

B$)$ a $=8$

C$)$ a $=10$

D$)$ This is a compilation error; you cannot compare array elements.

$7)$ If numbers is a two$-$dimensional array, which of the following would give the length of row r$?$

A$)$ numbers.length

B$)$ numbers.length$[$r$]$

C$)$ numbers$[$r$].$length$[$r$]$

D$)$ numbers$[$r$].$length

$8)$ Each array in Java has a public field named $\_\_\_\_\_\_\_\_$ that contains the number of elements in the array.

A$)$ size

B$)$ capacity

C$)$ length

D$)$ limit

Part B: State TRUE or FALSE:

$1.$ An array can hold multiple values of several different data types simultaneously.

$2.$ An ArrayList object automatically expands in size to accommodate the items stored in it$.$

$3.$ Once an array is created, its size cannot be changed.

$4.$ Java does not limit the number of dimensions that an array may have.

$5.$ Objects in an array are accessed with subscripts, just like any other data type in an array.
