Question

I need a program written in Java.

Write a simple line editor. Keep the entire text in an ArrayList object, one line in a separate index position. Start the program with entering EDIT file, after which a prompt appears along with the line number. If the letter I is entered with a number n following it, then insert the text to be followed on line n. If I is not followed by a number, then insert the text on the current line. If D is entered with two numbers n and m,one n, or no number then delete lines n through m, line n, or the current line. Do the same with command L, which stands for listing lines. If A is entered, then append the text to the existing lines or the last line. Entry E signifies exit and saving a text file.

Example:

Input file: textin.txt

The first line

And another line

EDIT testin

1>The first line

2>

3> And another line

4> I 3

3> The second line

4> One more line

5> L

1>The first line

2>

3> The second line

4> One more line

5> And another line     // This is now line 5, not 3

5> D 2                          // line 5, since L was issued form line 5

4> L                             // line 4, since one line was deleted

1>The first line

2> The second line

3> One more line

4> And another line

5>D 2 4

4>L

1>The first line

2>A

1> not done yet

2> L

1>The first line not done yet

2> E

Output File: textout.txt

The first line not done yet

The lines that are left or changed after entering E must be saved in new text file. textout.txt
