For the last two book giveaways I did, I promised I would pick a winner totally at random from the comments.

So you've done everything correctly by adding one to that number. Then took the integer part by using , then we have added 1 to it. I shall give you a start with the utility class: note the reason for the private constructor is explained in the. Our next method is getRandomInteger int maximum, int minimum , which returns a random integer between a given range. But wanted to make this website a bit more useful, in that it will take a low and high value and return a random number between those two values.

In this case, befote the comparision is validated java cast the int to double! This only works if they user types in anything but Mike or David. Standard Standard Draft Browser compatibility The compatibility table in this page is generated from structured data. I sugest you to read Oracle's tutorial Defining Methods on this Basicaly, it is a block of code that you can call anytime depending on the acess modifiers and some other rules. Getting a random integer between two values, inclusive While the getRandomInt function above is inclusive at the minimum, it's exclusive at the maximum.

As I said earlier, If you are interested in learning more about other random number generators in Java e. You can only generate positive random numbers using this method, if you need a negative random number you should use nextInt , nextLong or nextDouble method of Random class from java.
