Question
Chapter 11, Problem 10PE
Program Plan Intro
Reverse the file content
Program plan:
- Include the required header files in the program
- Define the “Reverse” class
- Define the “readLinesToArray” method
- Declare “lineList” as an “ArrayList” variable
- In “try” block, declare an object for “Scanner” class and pass the filename as an argument.
- Add the each lines to the “lineList” variable using “while” condition
- The “catch” block throws an error message if the file is not found.
- Return the value.
- Define “reverse” method
- Declare the string variable “reversed”
- Iterate “i” until it reaches length of the “line” variable
- Reverse each character in the file and store the reversed characters in “reversed” variable.
- Return the “reversed” variable
- Define “reverseAll” method
- Iterate “i” until it reaches length of the “lineOfLines” variable
- Call the “reverse” method and reverse each lines in the file
- Iterate “i” until it reaches length of the “lineOfLines” variable
- Define the “writeAll” method
- In “try” block, declare an object for “PrintWriter” class and pass the filename as an argument.
- Write all the lines in the file
- The “catch” block throws an error message if the file is not found.
- Define the main method
- Check the “args” length is less than 1
- If the condition is true, then display error message
- Otherwise, create an object of “readLinesToArray” method
- Call the “reverseAll” method with an argument
- Call the “writeAll” with the arguments
- Display the successive message.
- Define the “readLinesToArray” method
