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. 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> E

Output File: textin.txt

The first line

The second line

One more line

And another line
