Another way to do this problem besides using ASCII conversions is the following   String input    abc  toLowerCase    final static String alphabet    abcdefghijklmnopqrstuvwxyz   for int i 0  i  lt  input length    i         System out print alphabet indexOf input charAt i   1

First you need to write a loop to iterate over the characters in the string  Take a look at the String class which has methods to give you its length and to find the charAt at each index   For each character  you need to work out its numeric position  Take a look at this question to see how this could be done

This depends on the alphabet but for the english one  try this   String input    abc  toLowerCase      note the to lower case in order to treat a and A the same way for  int i   0  i  lt  input length      i       int position   input charAt i  -  a    1

String str    abcdef   char   ch    str toCharArray    for char c   ch       int temp    int c      int temp integer   96    for lower case     if temp lt  122  amp  temp gt  97          System out print temp-temp integer       Output      123456    Shiki for Capital UpperCase letters use the following code   String str    DEFGHI   char   ch    str toCharArray    for char c   ch       int temp    int c      int temp integer   64    for upper case     if temp lt  90  amp  temp gt  65          System out print temp-temp integer       Output      456789

Convert each character to its ASCII code  subtract the ASCII code for  a  and add 1  I m deliberately leaving the code as an exercise   This sounds like homework  If so  please tag it as such   Also  this won t deal with upper case letters  since you didn t state any requirement to handle them  but if you need to then just lowercase the string before you start   Oh  and this will only deal with the latin  a  through  z  characters without any accents  etc
