Information Systems (IS) headquartered in Orlando, Florida, employs approximately 4,100 employees throughout the United States. A-1 IS provides leading edge technologies, distributed computing, mainframe, micro, communication, and consulting services to its parent company A-1 Corporation, headquartered in Bethesda, Maryland, as well as to external customers including the U. S. government. In addition A-1 IS is responsible for the development and support of all the internal systems that support their day-to-day business processes and operations. Now that we have completed the preliminary investigation of the system and gained approval to proceed, we can attempt to gain a better understanding of the current system.
In this assignment we will use our results of Milestone 1, plus the Case background information, in order to perform cause-effect analysis. The results of this activity will provide us a better understanding of the problems, opportunities, and constraints of the current system.

This question involves a class named textfile that represents a text file. public class textfile { private string filename; private string filename; private arraylist words; // constructors not shown // postcondition: returns the number of bytes in this file public int filesize() { } // precondition: 0 < = index < words.size() // postcondition: removes numwords words from the words arraylist beginning at // index. public void deletewords(int index, int numwords) { } // precondition: 0 < = index < = words.size() // postcondition: adds elements from newwords array to words arraylist beginning // at index. pub lic voidaddwords(int index, string[] newwords) { } // other methods not shown } complete the filesize() method. the filesize() is computed in bytes. in a text file, each character in each word counts as one byte. in addition, there is a space in between each word in the words arraylist, and each of those spaces also counts as one byte. for example, suppose the words arraylist stores the following words: { mary had a little lamb; its fleece was white as snow. } the filesize() method would compute 4 + 3 + 1 + 6 + 5 + 4 + 6 + 3 + 5 + 2 + 5 as the sum of the lengths of each string in the arraylist. the value returned would be this sum plus 10, because there would also be 10 spaces in between the 11 words. complete the filesize() method below: // postcondition: returns the number of bytes in this file public int filesize() { }
