How do I generate random integers within a specific range in Java? 57 answers

You could use eg r.nextInt(101)

For a more generic "in between two numbers" use:

Random r = new Random();
int Low = 10;
int High = 100;
int Result = r.nextInt(High-Low) + Low;

This gives you a random number in between 10 (inclusive) and 100 (exclusive)

假设上限是上限，下限是下限，则可以在两个边界之间使用随机数r：

int r = (int) (Math.random() * (upper - lower)) + lower;

---

Er...

int Random = (int)(Math.random()*100);

if You need to generate more than one value, then just use for loop for that

 for (int i = 1; i <= 10 ; i++)
       {
        int Random = (int)(Math.random()*100);
        System.out.println(Random);
       }

If You want to specify a more decent range, like from 10 to 100 ( both are in the range )

so the code would be :

   int Random =10 +  (int)(Math.random()*(91));
   /* int Random = (min.value ) + (int)(Math.random()* ( Max - Min + 1));
  *Where min is the smallest value You want to be the smallest number possible to       
  generate and Max is the biggest possible number to generate*/
