Course Introduction:Java uses the random() function of the Math class to generate random numbers. In Java, we can use the random() function of the Math class to generate random numbers. The Math class is a built-in class in Java that contains some commonly used mathematical operation methods. Among them, the random() method is used to generate a random floating point number between 0 and 1. The basic syntax for using the random() function to generate random numbers is as follows: doublenum=Math.random();
