Chapter 6, Problem 33RE

Explanation of Solution

a.

Code to test that two array lists contain the same elements in the same order is as follows:

//Variable to check whether the elements are same or not

boolean same = true;

/*Check whether the two array lists contains same number of values or not */

if(values1.size() != values2.size())

{

    //Assign the value of “same” as “false”

    same = false;

}

/*loop through each element of two array lists and check whether both or same or not */

for(int x = 0; x < values1.size() && same; x++)

{

    //Check both array lists values are same or not

    if(value1...

Explanation of Solution

b.

Code to create a second array list that is empty and then loop over the first is as follows:

//Declare an integer array list

ArrayList<Integer> values2 = new ArrayList<Integer>();

/*Loop through each element in the “values1” array list and store the values into the “values2” array list */

for (int x = 0; x < values1...

Explanation of Solution

c.

Code to fill an array list with zeros, overwriting all elements in it is as follows:

//Loop through each element in the “values” array list

for (int x = 0; x <  values.size(); x++)

{

/* Overwrite all elements in the array lis...

Explanation of Solution

d.

Code to remove all elements from an array list is as follows:

//Remove all elements from the array list

while (values.size() > 0)

{

  values.remove(0);

}

Explanation:

In the above code,

• The “while” loop is used to remove all elements from the “values” array list...
