storing data in an array.

Mar 1 '07, 07:43 PM

Hi Guys,

this is the code that reads the data from a text file and displays it in a jsp.
iam trying to put the data in a array so that each time the code readfs the data the previous data is stored, however this is not working can someone please help.

Code:

<HTML>
<HEAD>
<TITLE>The result.....</TITLE>
</HEAD>
<BODY>
 
<%@ page language = "java" import="java.io.*"%>
 
<% try
	{
		
			
	String strPath ="W:/www/ee05u041/data.txt";
	String j;
	int []i;
	i=new int[10];

	for( i[0]; i[0]<10; i++)
{
   BufferedReader objReader = new BufferedReader(new FileReader(strPath));
		i[0] = objReader.readLine ();
 		j=Integer.parseInt(i[0]);
		
	while (i[0] != null)
	
	{
		out.println(j);
		j = objReader.readLine();
		i[0]=j;
	}
	
	}
	out.println(i[0]);
		out.println(i[1]);
			out.println(i[2]);
 
	catch(IOException e){} 
	}
%>	
 
</BODY>
</HTML>

(There is actually a jsp forum but....)

The way you are using the array is a little strange.....
Your forloop increments the VALUE of i[0]....

try changing the for loop to something like

Code:

for( int k=0; k<10; k++)
{
   BufferedReader objReader = new BufferedReader(new FileReader(strPath));
   i[k] = objReader.readLine ();
   j=Integer.parseInt(i[k]);
		
   while (i[k] != null)	
  {
    out.println(j);
    j = objReader.readLine();
    i[k]=j;
  }
	
}
out.println(i[0]);
out.println(i[1]);
out.println(i[2]);
