Get data from notepad and display it.

Asked By Smith Miller 10 points N/A Posted on - 04/05/2012

I need a little help in java programming. I will be using in my payroll system. I need a program in java who will let the user enter an employee code then all of the information about the employee having that code will appear. The program will get the information from a notepad file.

Example:

Enter Employee code: 110011

(If I enter the code the information of the employee who have that code will appear)

Employee name: John S.

Age:20

Position:Secretary

Rate per hour: 5.00$

Country: USA

I'll just want a sample code as my reference. Thanks

Get data from notepad and display it.

Hi Smith,

Here is a very simple solution for you.

 

import java.io.*;

class text_reader 

{

 public static void main(String args[])

 {

 

     try{

 

        // open the text file

        // you can specify a full path if the file 

        // is not located on the same folder

         FileInputStream fstream = new FileInputStream("textfile.txt");

         // inialize input stream

         DataInputStream dstream = new DataInputStream(fstream);

         BufferedReader reader = new BufferedReader(new InputStreamReader(dstream));

         String strLine;

         String fields [];

         fields = new String[6];

         // fields

         fields[0] = "Employee Code";

         fields[1] = "Employee name";

         fields[2] = "Age";

         fields[3] = "Position";

         fields[4] = "Rate per hour";

         fields[5] = "Country";

         System.out.println("Enter employee code:");

         InputStreamReader input = new InputStreamReader(System.in);

         BufferedReader inputreader = new BufferedReader(input);

         String sEmpSearchCode = inputreader.readLine();

         boolean bFound = false; 

         //read File Line By Line

         while ((strLine = reader.readLine()) != null)

         {

        

             // tokenize the string, match 1st element with our search string

             String[] tokens = strLine.split("\,");

             String sEmpCode = tokens[0];

             if(sEmpCode.compareTo(sEmpSearchCode) == 0)

             {

                 // we found it

                 // print it

                 bFound = true;

                 for (int index=0; index<tokens.length; index++)

                 System.out.println(fields[index] + " = " + tokens[index]);

                 break;

             }

            

         }

            //close the input stream

            dstream.close();

       

        if(!bFound)

            System.out.println( sEmpSearchCode + " not found");

        }

        catch (Exception e){//Catch exception if any

            System.err.println("Error: " + e.getMessage());

        }

    }

}

 

Create a textfile named "textfile.txt" on the same folder with your java program. The format is:

 

110011,John Shy.,20,Secretary,5.00$,USA

110100,Jon Doe,22,VP,100.00$,USA

 

The program reads it line by line and split the data using comma. 

 

I hope it helps.
