This article is about how to generate random numbers between arbitrary numbers in java. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Public static int cssjs (int a drawing int b) {Random rand=new Random (); int zhi; zhi=rand.nextInt (b)% (b-a+1) + a; return zhi;}

We observe the nextInt (int) method of its Random object and find that this method generates integers with random values between 0 and parameters. For example (suppose there is Random rand = new Random ()

Rand.nextInt (100); this line of code will generate a random number in the range 0 to 100. Interestingly, the value may be 0, but it cannot be 100. We use the interval representation of middle school math class, which is expressed as: [0100).

The explanation of the mathematical principle of generating random numbers in any range of values: first get the random number between 0-max, and then take the remainder of max-min+1, so that the result is 0 to max-min, and then add the minimum value min, which is the required random number. Suppose max = 100 leading mines. nextInt (100) should be a number between 0 and 100, and max-min+1 should be 51.

The number obtained by taking the remainder should be 0-50. Finally, the minimum number (50) should be 50-100. It corresponds to the assumed maximum and minimum numbers. You can assume other numbers to try.
