Question

Describe the effect of each of the following operations on object myList .

What is the value of myList.size() after each operation?

Figure the initial list consist of the following string names:

Bashful

Awful

Doc

Jumpy

Happy

Dopey.

Answer both questions.

myList.add("Pokey");

myList.add("Campy");

int i = myList.indexOf("Happy");

myList.set(i, "Bouncy");

myList.remove(myList.size() - 2);

String temp = myList.get(1);

myList.set(1, temp.toUpperCase());

Answer 1

Solution

Starting size is 6

myList.add("Pokey");

It add elements to end of the "myList"

after adding size is 7

myList.add("Campy");

It add elements to end of the "myList"

after adding size is 8

int i = myList.indexOf("Happy");

it returns the value 4 and it stored to integer 'i"

myList.set(i, "Bouncy");

then we set the element i(4) to "Bouncy" and size is 8

myList.remove(myList.size() - 2);

it will remove the item 6 that is "Pokey" and size is 7

String temp = myList.get(1);

now it will store "awful" in temp and size is 7

myList.set(1, temp.toUpperCase());

Now sets item1 to "AWFUL" and replacing "awful

therefore

final size is 7
