7. (10 points; 2 points each part) For each code fragment below, show a memory diagram that traces the program's execution and give the value in the array data and the int variable size (part e only) after the method has executed. Also, show the value of the data array under the line that says "show result here." a) /7 calling method int[] data = { 3, 6, 9 }; method(data, 7); / show what is in the array data at this point: public static void method int] source, int value) source[1] value; = Heap Main Stack Frame Identifier Address Contents Identifier |Address Contents 1000 1001 1002 1003 1004 1005 1006 1007 1008 1009 1010 1011 1012 101 102 103 Method Stack Franm Identifier Address Contents 200 201 202

Explanation / Answer

For part e .

The values in array after calling the method will be {0,0,3.1}

How ?

Before calling we are initializing array using for loop .

by i/2.

As loop will run three time .

iteration 1.

i=0

data[0]=i/2=0

iteration 2

i=1

data[1]=i/2=0

iteration 3

i=2

data[1]=i/2=1

so initially dat araay is {0,0,1}

size=3.

method is called with these values

and value at size-1 is changed means 3.1 is assigned at data[0] because of call by reference.

but size variable is called using call by value hence its value is not changed

so size will remain 3.
