Hi, does anyone know how to read the specified line from a text file? And by create a program, we can load what is write inside the text file and read line by line to show at the program.
Not really clear.

Do I understand well?
You want a program able to output contents of a file. That's it?If yes...
Another solution could be the use of a Scanner ,with your file as a parameter. http://java.sun.com/j2se/1.5.0/docs/api/java/util/Scanner.html
You should focus on hasnextLine() and nextLine() methods.
You could then easily print this directly... But is your program just about this? Will not you need to re-use these contents for other purposes? If so, you should store them somewhere... An easy solution would be the use of an ArrayList... http://java.sun.com/j2se/1.4.2/docs/api/java/util/ArrayList.html
You should focus on the constructor, add and get methods...
So:
- read file using Scanner
- Store contents in ArrayList
- print ArrayList
