machan umba ahala tiyenna niyama prashnayak! meka java lovers late hugak ona wei!
We all know to save data , we use databases such as SQL in every software. But the problem with this is If the data are saved in a database, User has to instal SQL sever with the software to work properly!
This is pointless Coz installing the database with the software is hard!
But Im gonna show you guys a way to save data in a text sheet without implementing databases!(This way is used by many modern softwares!!)
here it is...
//-------------------------------------------------------------------------
import javax.swing.JTextField;
import java.io.*;
import javax.swing.JOptionPane;
/**

*/
public class JavaApplication12 {
public void write(String text){
String theline=text;
try{
FileOutputStream fout;
//NOW ARE GIVING A PATH TO CREATE THE TEXT FILE, GIVE YOUR OWN PATH (THIS IS THE PATH FOR MY PC)
fout = new FileOutputStream ("C:\\Users\\Akhila\\Documents\\akhila docs\\MYTEXT.txt");
//PREVIOUS LINE HAS CREATED A TEXT FIILE CALLED MYTEXT.txt
new PrintStream(fout).println (theline);
fout.close();
}
catch(Exception e){}
}
}
//-----------------------------------------------------------------------------
NOW WE HAVE WRITTEN DATA TO A TEXT FILE NOW HERE THE CODING TO READ IT!
//-------------------------------------------------------------------------
import java.io.*;
public class JavaApplication12{
public String Read(){
String line="";
FileInputStream fin;
try
{
//give the path of the created file
fin = new FileInputStream ("C:\\Users\\Akhila\\Documents\\akhila docs\\MYTEXT.txt");
line=( new DataInputStream(fin).readLine() );
fin.close();
return line;
}
catch (Exception e)
{
return line;
}
}
}
//-------------------------------------------------------------------------------
Machan this is the way to do this! i know your using this coding for a small thing But By edting this code you can create a database in a text file and encrypt it also!!
ENJOY!!!

MACHAN MAMA UMBATA WEBPAGE EKAK READ KARALA EKE TIYANA TEXT EKA GANNE KOHOMADA KIYALA KIYANNAM!
this is how you read a URL!!!
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.*;
import java.io.*;
public class ReadWebPage {
public String readnow(String txt){
String LINexxx="";
//String LINe="";
String txt1=txt;
try{
String urltext = txt1;
URL url = new URL(urltext);
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String line = "";
while ((line = in.readLine()) != null){
// System.out.println(line);
String line1="";
//line1=in.readLine();
line1=line;
LINexxx=(LINexxx+"----------"+line1);
}
in.close();
return LINexxx;
}
catch (Exception e)
{
String Er="error is occured";
return Er;
//System.out.println(e.toString());
}
}
}
pass the web address with http to readnow method!
ex=http://www.google.lk/

if you can put some cording regarding my problem..please..
Malla i can give u coding a print a text file using java. when you click tha button, yur doc will be printed!
but malla for direct printing you need to know the bit patterns.
search google for tht.

}
if you dont get the methods follow this steps.

Have to add dynamically man....If user needs 20 button code should be automatically generated. No of buttons is unknown untile runtime.
Imagine that we have to create a realtime IDE....

You dont know the first thing about java.Its a pure object oriented programming language. Maybe ur a software engineer But machan never frgt tha concept of JAVA.
I dont wanna argue with yu. But if u wanna bet ill make yur program with ma concept. brother, i just gave tha sample coding coz i thought ur capable of editing it.. U can do ur project with ma coding U jus have to use String Manipulation. No of items user wanna add is given at the runtime and its passed to ma class and for-loop will run to add them in the positions he picks. Just lik that you can do that.
BTW u hav no idea about whats IDE
Use collections to hold the text fields or whatever filed you want hold.. but this may differ according to your needHave to implement a java app with ability to add new textbox, lables at runtime according to user interaction.
If u can post sample code.
Dont say question is not clear
