Read data line by line from a text file?

[ddddd]

Hi,

Can you show me the best code to read the data in a txt file:
(note: '*' represents space(s) or/and tab(s), 'head11' represents string '1111' is int and '1.111' is
float)

head12 * head12 * head13 *head14
1111 * 1.111 * 1.222 * 1222
2111 * 2.111 * 2.222 * 2222
.........
head22 * head22 * head23 *head24
1111 * 1.111 * 1.222 * 1222
2111 * 2.111 * 2.222 * 2222
.........

Hi ,
Here is the code for reading the line data from ur txt file. i have given the delimiter as a blank space.. u can change it to tab and check this program. Hope this helps .

import java.io.*;
import java.util.*;

public class TxtReader
{
public static void main(String[] args) throws Exception
{
File txtFile = new File("filepath.txt" // give ur file name here.
FileReader fr = new FileReader(txtFile);
BufferedReader br = new BufferedReader(fr);
String strLine = br.readLine().trim();

while(strLine != null)
{

if(strLine.equals("&quot)
{
// if blank line
continue;
}
else
{
String[] strTokens = getTokenArray(strLine," ",false);
for(int i = 0 ; i < strTokens.length; i++)
{
System.out.println(strTokens);
}
}
strLine = br.readLine();
}
}

private static String[] getTokenArray(String strString, String strDelim, boolean bIncDelim)
{
String strTokens[];
StringTokenizer oStrTkn;
int iCount = 0;
if(strString == null || strString.length() == 0)
{
return null;
}
oStrTkn = new StringTokenizer(strString, strDelim, bIncDelim);
strTokens = new String[oStrTkn.countTokens()];
while(oStrTkn.hasMoreTokens())
{
strTokens[iCount] = oStrTkn.nextToken();
iCount++;
}
return strTokens;
}
}
