Question

Assume that rand is an object of the Random class. Which of the following statements controls the generation of the random numbers, such that each execution generates the same sequence of numbers?

a. rand.setSeed(3333);
b. rand.setSequence(3333);
c. Random rand = new Random(3333);
d. Both A and C

Answer 1

The statements that ensure the generation of the same sequence of random numbers across different program executions are 'rand.setSeed(3333);' and 'Random rand = new Random(3333);', corresponding to answer 'd. Both A and C'.

Step-by-step explanation:

The statement that controls the generation of random numbers in such a way that each execution generates the same sequence of numbers is:

• rand.setSeed(3333);
• Random rand = new Random(3333);

Therefore, the correct answer is d. Both A and C. The setSeed method is used to set the seed of the random number generator, which is a value that determines the starting point of the sequence of random numbers. By setting the seed to a specific value, it becomes possible to produce the same sequence of numbers across different runs. This is particularly useful for debugging or for creating predictable behavior in programs that rely on random number generation.
