Java: generating random number in a range

Hello,

I am trying to generate a random number with Java, but random in a specific range. For example, my range is 5-10, meaning that 5 is the smallest possible value the random number can take, and 10 is the biggest. Any other number in between these numbers is possible to be a value, too.

In Java, there is a function random() in the Math class, which returns a double value between 0.0 and 1.0. In the class Random there is a function nextInt(int n), which returns a random value in the range of 0 (inclusive) and n (exclusive). I couldn't find a method, which returns a random value between two numbers.

I have tried the following things, but I still have problems: (minimum and maximum are the smallest and biggest numbers).

Solution 1 :

randomNum = minimum + (int)(Math.random()*maximum);

problem: randomNum takes is assinged values numbers bigger that maximum

Solution 2 :

Random rn = new Random();
int n = maximum - minimum + 1;
int i = rn.nextInt() % n;
randomNum =  minimum + i;

problem: randomNum takes is assigned values smaller than minimum.

Could you suggest how to solve my problem, or point me to some references? I have tried also browsing through the archive, and found:

• http://stackoverflow.com/questions/288739/generate-random-numbers-uniformly-over-entire-range

but I couldn't solve the problem.

Thank you.

One standard pattern for accomplishing this is:

Min + (int)(Math.random() * ((Max - Min) + 1))

The java Math library function Math.random() generates a double value in the range [0,1). Notice this range does not include the 1.

In order to get a specific range of values first you need to multiply by the magnitude of the range of values you want covered.

Math.random() * ( Max - Min )

This returns a value in the range [0,Max-Min).

For example if you want [5,10] you need cover 5 integer values so you use

Math.random() * 5

This would return a value in the range [0,5)

Now you need to shift this range up to the range that you are targeting. You do this by adding the Min value.

Min + (Math.random() * (Max - Min))

You now will get a value in the range [Min,Max). But this is still doesn't include max and you are getting a double value. In order to get the max value included, you need to add 1 to your range parameter (Max - Min) and then truncate the decimal part by casting to an int. This is accomplished via:

Min + (int)(Math.random() * ((Max - Min) + 1))

And there you have it. A random integer value in the range [Min,Max].
