Using Delimiters to extract multiple characters

[amogh.max]

My code performs separation of "S12T00832B86*N1C0~S12*T0*0832*B*86*N1C0~"...Next i need to separate data between the "*" and utimately insert it into the database(ms-Access).i would like to recieve some code lines for that. Basically now the entire string i.e"**S12*T0*0832*B*86*N1C0" is being inserted into a column.i need to insert "S12" "T0" etc into separate columns.

public static void main(String[] args) throws IOException {
    String token1 = "";// create token1 (deceleration only)
    List<String> temps = new ArrayList<String>();// Array Deceleration only
    @SuppressWarnings("resource")
    Scanner inFile1 = new Scanner(new File("2.txt")).useDelimiter("~");//reading text data separated by (~)
    while (inFile1.hasNext()) {// while loop
      token1 = inFile1.next();// find next line in inFile1
      temps.add(token1); 
    }   
    inFile1.close();
    String[] tempsArray = temps.toArray(new String[0]);

Use String's split method

if i split how to connect to this code.

 PreparedStatement ps = con.prepareStatement("insert into testing (fileName)values('"+s+"')");//inserting data

here "s" is the entire"**S12T00889B99*N1C0".here's my complete code

import java.io.File;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class simplewrite {

    public static void main(String[] args) throws IOException {
    String token1 = "";// create token1 (deceleration only)
    List<String> temps = new ArrayList<String>();// Array Deceleration only 
    @SuppressWarnings("resource")
    Scanner inFile1 = new Scanner(new File("C:\\Users\\amoghmax\\Dropbox\\IIT Kharagpur Project\\sensornetworks\\2.txt")).useDelimiter("//*");//reading text data separated by (~)

      while (inFile1.hasNext()) {// while loop
      token1 = inFile1.next();// find next line in inFile1
      temps.add(token1); 
    }   
    inFile1.close();
    String[] tempsArray = temps.toArray(new String[0]);
    for (String s : tempsArray) {
      try
      {
              Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");//Data Source Driver
              Connection con=DriverManager.getConnection("jdbc:odbc:testing");//Data Connection
              PreparedStatement ps = con.prepareStatement("insert into testing (fileName)values('"+s+"')");//inserting data
              System.out.println(s);//printing inserted data
              System.out.println("inserted");//insertion confirmation
              ps.executeUpdate();
              con.close();
      }
      catch (Exception e)
      {
          System.out.println(e);
      }      
    }
  }
}

how do i store the broken data into something(not sure what to store it in) and insert it into column 2,column 3...

[JamesCherrill]

It splits the data into an array of Strings, so the first col's data is in array[0], the second in array[1] etc.

ps: Re your SQL code:
You create a new connection for each line of data you add. That's horribly inefficient. Create the connection before enetering the loop, and close it after leaving the loop.

     catch(Exception e)
      {
          System.out.println(e);
      }      
    }
  }

Refined code.working on the the split() now.

[JamesCherrill]

Yes, that's much better!

ps line 37 e.printStackTrace(); gives you more information about any error than just a println(e)
