The seed is a number that is used to initialize the random generator. More specifically: A random Generator is an algorithm which uses its own output as an input to generate the next random number, which will be used as input for the next one and so on. It is clear that a random number generator needs the first number to start work, that's called THE SEED. In principle there is not any limitation in choosing the seed. It can be <1, >1 or even something like 34561345567354. 

My question is ..... do they pick a number in the last draw sequence?

Stay In The Vortex, you'll be happy you did ..... Random? Seriously? You want me to believe that?

    run:
    8
    5
    0
    1
    9
    4
    3
    4
    BUILD SUCCESSFUL (total time: 0 seconds)

    Seed is optional.

    r.nextInt(10); //A digit.

    Long seed with long simple type.

    long: The long data type is a 64-bit two's complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1. Use this data type when you need a range of values wider than those provided by int. The Long class also contains methods like compareUnsigned, divideUnsigned etc to support arithmetic operations for unsigned long.

      Serge your wealth of programming and knowlegde AKWAYS amazes me   I understand the math but what are you telling me?  That THIS is there programming sequence or an example of hiw a seed works?

        Program it and you'll know about.
