Question: 1 / 510

How can you ensure generating a different sequence of random numbers each time in Java?

Using System.currentTimeMillis() as a seed

By using System.currentTimeMillis() as a seed, the random numbers will be generated based on the current system time. This ensures that each time the code is run, a different seed value will be used, resulting in a different sequence of random numbers. Option B is incorrect because not providing a seed will result in the same sequence of random numbers being generated each time the code is run. Option C is incorrect because hardcoding a seed value will also result in the same sequence of random numbers being generated each time. Option D is incorrect because calling reset() on a random object will only reset the seed to its initial value, and therefore, result in the same sequence of random numbers being generated each time.
