What is the method for generating random numbers in Java?

There are two common ways to generate random numbers in Java: using the Math.random() function and using the Random class.

1. Utilize the Math.random() function, which generates a random floating-point number between 0.0 and 1.0. To obtain a random integer within a specific range, multiply the returned value by the size of the range and round it to the nearest whole number.
2. For example, to generate a random integer between 1 and 10, you can use the following code:
3. Generate a random number between 1 and 10 and store it in the variable “randomNumber”.
4. Using the Random class:
   The Random class offers a more flexible and powerful random number generation capability. By creating a Random object, you can use various methods to generate different types of random numbers.
5. For example, to generate a random integer within a given range, you can use the nextInt(int bound) method.
6. Create a new random number generator and generate a random number between 1 and 10.
7. The nextInt(int bound) method returns a random integer greater than or equal to 0 and less than bound. By specifying different bound values, you can generate random numbers within different ranges.

It is worth noting that the random numbers generated by Math.random() are pseudo-random, while the ones generated by the Random class are true random numbers. Generating true random numbers can be less efficient, so when needing to generate a large amount of random numbers, it is recommended to use the Math.random() function.
