Question

Programming Problem 3 – CycleFileInput Revisit the Cycle class in Unit 3. Modify your application such that the properties will be read from a text file called “CycleIn.txt”. Directions Examine your application for the class called Cycle. • Add an appropriate throws statement in the main method. • Create a reference to a File class with the appropriate name of a text file (Cycle.txt). Note: Cycle.txt was created in the previous assignment, CycleFileOutput. • In your code, check that the text file does exist. • Input the values from the file to memory. • Close the file. Verify the contents were written to the text file using notepad (or any word processor)

Explanation / Answer

The requirement not crystal clear. But I have tried my best to give the best solution. Please comment if anything wrong or you want modifications in the code.

code:-

-------------

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.Scanner;

public class Cycle {

static File f = new File("");

static String s = f.getAbsolutePath();

static File cycleFileInput = new File( s+"/Cycle.txt"); //Taking file path

public static void main(String[] args) throws IOException {

if(cycleFileInput.exists()) { //Checking for file existence

System.out.println("Yes.. File exists");

}

Scanner sc = new Scanner(cycleFileInput); //Reading file

while(sc.hasNextLine()) {

System.out.println(sc.nextLine());

}

//Writing text to file

FileWriter fw = new FileWriter(cycleFileInput, true);

PrintWriter pw = new PrintWriter(new FileWriter(cycleFileInput, true));

pw.append(" This is to modify...");

//Closing the streams

sc.close();

pw.close();

}

}
