// randomly generating an integer between 1 and 100
int randomNumber＝(int)(Math.random()*100)+1；
System.out.println(randomNumber)；
Random () method is used to generate random numbers
There is also a method using the Random class.
Random (): a new random number generator is created.
Random (long seed): a single long seed is used to create a new random number generator.
The first construction method is to use the number of milliseconds of the default current system time as the seed number:
Random r1＝new Random()；
Random random＝new Random()；
int randomNumber1＝random.nextInt(100)；
the second method is to use the seed number specified by itself
Random random1＝new Random(100)；
for(int i＝0；i<10；i++){
System.out.print(random1.nextInt(10)+"")；
}
It is found that the random number generated each time is the same (so this is a pseudo-random number) as long as the seed number is consistent with the parameters in nextpint ().
