Equivalent method in java (numpy.random.normal(mean,var))

Question

Is there any method in java that is equivalent to numpy.random.normal(mean,variance).

Answer 1

You can use the java.util.Random class:

Random r = new Random();
double randomValue = mean + r.nextGaussian()*std_dev;

Note that if you need multiple random values, you can use r multiple times. You can also supply the constructor with a specific seed Random r = new Random(1234);.
