Question

Please help! I need help modifying a program. The existing program does the following:

- Three instance variables that are arrays of type String. Each array should hold at least 12 Strings. The three arrays will hold data read from three different files, described below.

- A method that opens three input files (named settings.txt, actions.txt and people.txt – see attachments) and reads their data into the 3 arrays (put actions in the action bag, etc.)

- A method that generates and prints out “headlines” consisting of strings pulled randomly from each of the bags, in the following order: people, actions, settings: in other words, randomly choose one people string, then randomly choose one action string, then randomly choose one settings string, and print them all out as one string.

- A main method that creates a Headlines object, prints out a headline, then prompts the user to see whether or not to continue; the program should continue to run as long as the user chooses to see more, and terminates when the user chooses to quit.

****** I would like to add the following capabilities:

- Keep track of which phrases in each file have been used, and don’t re-use them until all phrases have been used

- Allow the user to save any headlines s/he likes in a separate output file ******

Here is the existing code:

import java.io.*;
import java.util.Random;

public class HeadLines {
private String [] actions, people, settings;
private final int LENGTH = 12;
private int line;

public HeadLines()
{
line = 0;
actions = new String[LENGTH];
people = new String[LENGTH];
settings = new String[LENGTH];
}

public void readFiles() throws IOException{
String str;
FileReader fr = new FileReader("/Users/ribbit/Desktop/actions.txt");
//FileReader fr = new FileReader("actions.txt");
BufferedReader br = new BufferedReader(fr);
str = br.readLine();

while (str != null || line < LENGTH){
actions[line] = str;
line++;
str = br.readLine();
}
line = 0;

fr = new FileReader("/Users/ribbit/Desktop/people.txt");
//fr = new FileReader("people.txt");
br = new BufferedReader(fr);
str = br.readLine();

while (str != null || line < LENGTH){
people[line] = str;
line++;
str = br.readLine();
}
line = 0;

fr = new FileReader("/Users/ribbit/Desktop/settings.txt");
//fr = new FileReader("settings.txt");
br = new BufferedReader(fr);
str = br.readLine();

while (str != null || line < LENGTH){
settings[line] = str;
line++;
str = br.readLine();
}
line = 0;
}

public void printRandomSelection(){
Random rand = new Random();
int num1, num2, num3;
num1 = rand.nextInt(LENGTH);
System.out.print(people[num1] + " ");
num2 = rand.nextInt(LENGTH);
System.out.print(actions[num2] + " ");
num3 = rand.nextInt(LENGTH);
System.out.println(settings[num3] + ".");
}
}

THANK YOU!!!!
