RANDOM DOUBLE JAVA
Generate Random Double Values Between 0 and 1 in Java
We can use this class to generate random numbers too. Math.random () is the static function that returns random numbers between 0 and 1. Here, 0 is inclusive of the generated values, while 1 is always exclusive. In the following example, we use Math.random () to generate random values of type double. In the output, we can see the values are all ...

Java Random double in interval [-1000, 1000] - Stack Overflow
2 possibilities: [less dense]: multiple your results by 2000, and subtract 1000 from the result. It won't be as 'dense' as possibility 2. get a random int in range [-1000,999], and add a random double in range [0,1]. Note that possibility 2 ensures better randomness and better 'density' of your numbers, at the cost of 2 random calls [which ...
How to Create a Random Double Value in Java? - TutorialKart
Java – Create Random Double Value. To create a random double precision number in Java, use Random.nextDouble () method. Create java.util.Random class object and call nextDouble () method on this object. nextDouble () returns a randomly generated double precision number between -1.0 and 1.0. In the following example, we will create a random ...

We can also generate random doubles by using ThreadLocalRandom. Example:
Java Random doubles(double randomNumberOrigin, double randomNumberBound ...
The method doubles (double randomNumberOrigin, double randomNumberBound) is an overloaded method of doubles () wherein on this method requires two input which is randomNumberOrigin and randomNumberBound. By calling this method a pseudorandom double value is generated as if it’s the result of calling the following method with the origin and bound:

Fastest way to generate a random double number in java
In a project in which I'm working for, I'm required to either generate n random double numbers (depending from what the input file says) or converting them to doubles if I have them from my input file. Those numbers should have only 2 decimals after the comma (ex.: 0.98). I know that in Java 8, there are 2 ways of doing this:
Random (Java SE 18 & JDK 18) - Oracle
The algorithms implemented by class Random use a protected utility method that on each invocation can supply up to 32 pseudorandomly generated bits. Many applications will find the method Math.random () simpler to use. Instances of java.util.Random are threadsafe.
