This question involves a class named filetext that represents a text file.
public class filetext
{
private string filename;
private int filebytes;
private arraylist‹string› wordlist; // the contents of the text file
// constructors not shown
// postcondition: calculates the number of bytes in this file and updates
// the instance variable filebytes
public void filesize()
{
}
// precondition: 0 < newwords. length < wordlist. size ()
// postcondition: elements from the newwords array are placed into consecutive
// odd index positions of the wordlist arraylist
// postcondition: the value of filebytes is updated
public void mergewords(string[] newwords)
{
}
// other methods not shown
}
the wordlist arraylist stores the words (tokens) found in a text file. suppose wordlist contains the following elements:
[mary, had, a, little, lamb]
the filesize method; the size of the file is computed in bytes. each character in a word counts as one byte. in addition, there is a space in between each word, and each of those spaces also counts as one byte. for the example above, the filesize method would compute 4 + 3 + 1 + 6 + 4 as the sum of the lengths of each string in the arraylist. the value of filebytes would be this sum plus 4, because there would be 4 spaces in between the 5 words.
for the mergewords method, assume the values for the newwords array are as follows:
{"one", "two", "three"}
after the method has executed, filebytes will have an updated value, and wordlist would contain the following elements:
[mary, one, had, two, a, three, little, lamb]
