title: Reading data from Excel using Java
body: <p>I have 2 columns in an excel sheet, A and B, and I need to divide column A (randomly) into 2 and calculate the average of the first and second halves of column B separately. Then I need to divide column A again but each time moving with one cell downwards and calculate the averages etc. Can this be done using Java only? Since I am finding you have to use software like Apache and I have never used them.</p>
  
  <p>Thanks</p>
