title: Reading in a text file upto specific number of characters
body: <p>::A Newbie here::</p>
  
  <p>I've a text file having text like</p>
  
  <p><strong>COM22: 15:55:09 20.09.2013VOLT=224</strong></p>
  
  <p>I want to read this line and separate it to get </p>
  
  <p><strong>15:55:09 20.09.2013</strong> </p>
  
  <p>and then </p>
  
  <p><strong>Volt=224</strong></p>
  
  <p>At this time I'am using br.readLine() which reads the whole line...Is there any way I can restrict br.readline() to start from certain numbered chracter (e.g. 4th character in line)and end on a certain(e.g. 8th)???</p>
