Because when we throw it, we get a random number between 1 to 6. Many applications will find the method Math.random () simpler to use. Instances of java.util.Random are threadsafe. However, the concurrent use of the same java.util.Random instance across threads may encounter contention and consequent poor performance. Consider instead using ThreadLocalRandom in multithreaded designs. The Random class of Java located in the java.util package will serve your purpose better. It has some nextInt () methods that return an integer.

Math.max(x,y) The Math.max(x,y) method can be used to find the highest value of x and y: Example Math.random() returns a random number between 0.0 (inclusive), and 1.0 (exclusive): The Math.random() method in Java returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0. The returned values are chosen pseudorandomly with (approximately) uniform distribution from that range. Java Math.random () The Java Math.random () method returns a random value that is greater than or equal to 0.0 and less than 1.0. The syntax of the random () method is: Math.random () Note: The random () method is a static method.
