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

Before starting the course, I asked the students to fill out a questionnaire that reflected their understanding of some of the concepts in Python. Some topics ("If/else Control Flow" or "definition and use functions") are not problematic for most
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
1. Question
Given a random number generator, this generator can generate a random number ranging from 1 to 5 () evenly. How can we use this generator to generate a number ranging from 1 to 7?
2. Ideas
Method 1: generate two (1, 5) random numbers.

Java random number SummaryRandom numbers are widely used in practice. For example, a fixed-length string or number
The generator and yield keywords may be one of the most powerful and difficult-to-understand concepts in Python (perhaps none), but it does not prevent yield from becoming the most powerful keyword in python, which is very difficult for beginners to
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
