#JAVA RANDOM PICK A NUMBER BETWEEN 1 AND 3 CODE#
The following code generates a random integer number between 1 and 10 (1 <= x <= 10): int x = 1 + (int) (Math.random() * 10) And the following code snippet generates 10 random integer numbers between 1 and 10: for (int i = 1 i <= 10 i++) And using ints() method of Random class: IntStream ints = random. Generate random numbers using Math.random()The static method random() of the Math class returns a pseudorandom double value in the range from 0.0 to 1.0. However, you can use it for cases in which true randomness and security are not required. The generated numbers are parts of a very large sequence so they appear to be random, but they are not true random numbers.
