Hi Shekhar,

First I would like to explain you what is Pseudo code.

Pseudo Code:
Pseudo code is a notation which is used to express the intention of your program. While writing Pseudo code, we do not care about syntax. What is important for us is to carry out the intention of the program.

Example of ATM withdraw transaction pseudo code:
Check the available balance in user's account.
if the selected account's balance is greater than the requested amount
reduce balance by requested amount and dispense the cash
else
display error message saying that no sufficient funds
end if

Coming back to your question: How to convert Java program into Pseudo code?
Ans: Very simple !
Understand your program logic properly
What is the user input
What needs to be generated as output
What are the decision that your program is taking based on user input... etc and list goes on :-)
Please let me know in case if you still have any confusion.

Thanks,
Siva
