how to make random number generator

Method 1(Data Type) (minimum value + math. Random () * (maximum value-Minimum value + 1 ))Example:(INT) (1 + math. Random () * (10-1 + 1 ))INT-type numbers from 1 to 10Method 2Obtain Random NumberFor (INT I = 0; I {System. Out. println (INT) (1 +

This paper mainly introduces 3 kinds of methods of obtaining random number in Java, mainly using random () function to realize Method 1 (data type) (Minimum +math.random () * (maximum-min +1)) Example: (int) (1+math.random () * (10-1+1))

RandomThe random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's programming Art of 3.2.1)If two random instances use the same seed, and

In the previous blog, we learned about the real random number generator based on physical phenomena, however, the real random number generation is slow, for the actual computation needs, the random number in the computer is generated by the program

About Random Number Security 0x00 I talked to my friends about an interesting phenomenon. during the school recruitment interview in the last two years, most of my students did not have any basic cryptographic knowledge, even those with some

One. In J2SE we can use the Math.random () method to produce a random number, the resulting random number is a double between 0-1, we can multiply him by a certain number, for example, multiplied by 100, he is a random within 100, this is not in the
