/*****************************************************************
** DemoStringMethods - demonstrate common string methods
**
** The following string methods are demonstated:
**
**    length()       - return the lenght of a string
**    toUpperCase()  - convert a string to uppercase characters
**    toLowerCase()  - convert a string to lowercase characters
**    substring()    - extract a substring from a string
**    charAt()       - extract a single character from a string
**    indexOf()      - return the index of a specified character
**    compareTo()    - return the lexical difference between string
**
** This program generates the following output:
**
**    12
**    world
**    HELLO, WORLD
**    hello, world
**    w
**    3
**    35
**    -1
**    false
