Hi,
1. Is there any Method in Java which gives the Unicode value of any characters etc. If there is please let me know what it is. If there isn't any then how to find out what is the unicode value of suppose 'A'. Are we supposed to remember the unicode values. Please let me know.
2. Khalid had shown in his book converting of Octal and Hexadecimal Numbers to Decimal.
How to convert the decimal values to Octal or Hexadecimal values. Please let me know.
Thanks.
chandu.

Hi chandrashekar,
1. You are not expected to know all the Unicode characters; however, you should be familiar with the concept of Unicode escapes (see JLS §3.3) and the escape sequences for character and string litrals (see JLS §3.10.6).
2. I have some notes on bin/oct/hex/decimal conversions at http://www.janeg.ca/scjp/oper/binhex.html which may help.
