    I want to generate a double value in java, with up 10 decimal spaces. I know how to use the standard java random number generator to get numbers in between a specific range, but I dont know how to shift decimal places so that I can have decimals and whole numbers like 123456.000123. This is probably simple but the only way I know how to do this at the moment would be to generate each digit separately and put them together which is pretty inefficient. Any suggestions would be greatly appreciated!

    Do you need it to specifically have that format? With that many whole number places and that many decimal places filled?

    Check Random.nextDouble() and use the precision you need.

    What are you going to do with it? You might be better off using BigDecimal
