Simple File Handling System

Here are the steps that I made in creating my Simple File Handling System.

          For the main class, I used the JFrame form. The following codes composed the main methods of my file handling system which include the Writing, Reading and Deleting the entire file.

         Below is the design that I formulated in JFrame form. The Palettes that I used are also indicated below.

          In addition, I created another class (for the Reading function) within the main class above. For reference, here are the codes:

____________________________________________________________________

package textfiles;

import java.io.IOException;

import java.io.FileReader;

import java.io.BufferedReader;

public class Readfile {   

      private String path;   

      public Readfile(String file_path){       

      path=file_path;          

}      

int numberOfLines = 4; 

int readLines() throws IOException{       

      FileReader file_to_read = new FileReader(path);                   BufferedReader bf=new BufferedReader(file_to_read);               String aLine;              

      while (( aLine = bf.readLine()) != null){    

            numberOfLines++;}  bf.close();  return numberOfLines;

       }
public String[] OpenFile() throws IOException {                         FileReader fr =new FileReader(path);                              BufferedReader textReader = new BufferedReader(fr);              String[ ] textData = new String[numberOfLines];                  int i;                   

        for (i=0; i < numberOfLines; i++) {                     

          textData[ i ] = textReader.readLine();

         }                   

textReader.close();return textData;
   } 

}

          Next, I also created another class for the Writing function. I still located this in the main class. The codes are as follow:

____________________________________________________________________

package textfiles;

import java.io.FileWriter;

import java.io.PrintWriter;

import java.io.IOException;

public class WriteFile {

    private String path;

    private boolean append_to_file=false;

    

    public WriteFile(String file_path){

        path = file_path;

    }

    

    public WriteFile(String file_path, boolean append_value){

            path = file_path;

            append_to_file=append_value;

    }

    public void writeToFile( String textLine ) throws IOException {

        FileWriter write = new FileWriter (path, append_to_file);

        PrintWriter print_line = new PrintWriter(write);

        

        print_line.printf("%s" + "%n", textLine);

        print_line.close();

    }

    }

      Finally, the output of my program is:
