    Firstly use the [code*][/code] tags when posting code.

    Second, remember, a char is a number associated with a letter, if you convert the string to an array of chars, you can xor each letter using the ^ operator.

    hello sir,
    I need to develop the below lines...1)message1=Hash(ID) xor number

    string like hello and display equivalent number
    Can you give some examples of the numbers that should be displayed for a String?
    Will each String have a unique number or are there possible collisions where two Strings can have the same number?
    If you don't understand my answer, don't ignore it, ask a question.

    i am doing my academic project.
    for every string it has to generate equivalent unique number..
    for example vehicle 1 and vehicle 2.so the numbers must be unique with each other and again i want that string by using the numbers...

    every string it has to generate equivalent unique number..
    Can you use the char value of the characters in the String to generate the number?
    I assume that there is no limit to the size of the number. For example int has 2 billion values which would not hold a large enough number. You'd have to use BigInteger variables to hold the values.
