Chapter 21, Problem 4PE
Program Plan Intro
Random access file to reverse all lines of a file in place
Program plan:
- Import necessary packages.
- Create a class “LinesReverserTest”,
- Define the “main()” method.
- Execute “try” statement,
- Create a “Scanner” object.
- Prompt the user to enter the name of file.
- Get the name of file from the user.
- Call the method “reverseLines()”.
- Catch if exception occurs,
- Print the exception.
- Execute “try” statement,
- Define the method “reverseLines()”,
- Create random access file.
- Initialize the variable.
- Declare the variable for the position.
- Execute a loop,
- Get the file pointer.
- Call the “seek()” method.
- Create a loop,
- Write the reversed line into the output.
-
- Call the method to print new line character into the output file.
- Close the file stream.
- Define the “main()” method.
