BufferedWriter not writing ALL the information

Question

I am making a simple tutorial program in which the user inputs some data, then that data is written into a textfile, then the textfile is read and the data displayed. However, not all of the data is being written into the textfile. Please view the following:

This is my code:

package chasi.fecalMatter.ExcrementalProgram;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import javax.swing.JOptionPane;

public class RedundantExcrement {

    static String inputName = JOptionPane.showInputDialog("Please input your FULL name:");
    static String inputUsername = JOptionPane.showInputDialog("Please input your desired Username:");
    static String inputJobTitle = JOptionPane.showInputDialog("Please input your Job title:");
    static String inputSalary = JOptionPane.showInputDialog("Please input your monthly salary:");

    static int convertedSalary = 0; /*Convert salary from String to int*/
    static int benefitDeduction = 0;

    static String empFileName = inputUsername+"INFO";
    static BufferedWriter bwriter = null;

    public static void main (String[] args) throws IOException {
        //Catch NumberFormatException.
        try {
            Integer.parseInt(inputSalary);
        } catch (NumberFormatException nfEx) {
            JOptionPane.showMessageDialog(null, "Please ensure that " +
                    "your salary is entered in NUMERIC form.", "ERROR!", 2);
            return;
        }

        //Specify instructions as regard salary -to- Benefit deduction ratio
        if (convertedSalary >= 3500) {
            benefitDeduction = 300;
        } else {
            benefitDeduction = 180;
        }

    try { /*Catches IOException AND NullPointerException*/ 
            FileWriter fwriter = new FileWriter(empFileName);
            bwriter = new BufferedWriter(fwriter);

            bwriter.write(inputName);
            bwriter.newLine();
            bwriter.write(inputJobTitle);
            bwriter.newLine();
            bwriter.write(inputSalary);
            bwriter.newLine();
            bwriter.write(benefitDeduction);
            bwriter.newLine();
            bwriter.write("----------");
            bwriter.newLine();              
        } catch (IOException | NullPointerException ionpEx) {
            JOptionPane.showMessageDialog(null, "An ERROR has occured", "ERROR!", 2);
            return;
        } finally { /*CLOSE the writer*/                
            try{
                if (bwriter != null) {
                    bwriter.close();
                }
            } catch (IOException ioEx2) {
                JOptionPane.showMessageDialog(null, "ERROR!");
                return;
            }
        }
    }
}

As you can see, I use the int convertedSalary to convert the user-inputted inputSalary from a String into a number. In my method, I use

try {
    Integer.parseInt(inputSalary);
} catch (NumberFormatException nfEx) {
    JOptionPane.showMessageDialog(null, "Please ensure that " +
            "your salary is entered in NUMERIC form.", "ERROR!", 2);
    return;
}

In order to covert it. It is later (supposed) to be written by the BufferedWriter.

I also have this code:

try {
    Integer.parseInt(inputSalary);
} catch (NumberFormatException nfEx) {
    JOptionPane.showMessageDialog(null, "Please ensure that " +
                "your salary is entered in NUMERIC form.", "ERROR!", 2);
    return;
}

In order to change the value of my benefitDeduction depending on the value of the user's salary.

HOWEVER, the benefitDeduction is written into the text file, but instead, I get this:

Thanks if you can help!

Answer 1

Look at the API.

public void write(int c)
   throws IOException

Writes a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored.

This means that the int is actually a char and will be converted according to Unicode/ASCII table.

To write the integer value use bwriter.writer(String.valueOf(benefitDeduction));
