What is the purpose of the Math class in Java?

The Math class in Java is a built-in class that provides a wide range of mathematical operations and functions. It allows Java programmers to perform mathematical tasks and calculations easily without writing complex code. The Math class is part of the Java standard library and can be used in any Java application without the need for importing external libraries.

The Math class provides static methods for mathematical operations such as trigonometry, logarithms, exponents, square roots, and more. These methods are invoked using the class name and are independent of any instance of the class. This means that you don't need to create an object of the Math class to use its methods.

One of the most commonly used methods in the Math class is the random() method which generates a random number between 0.0 and 1.0. Other useful methods include ceil() and floor() which round up and down to the nearest integer, respectively. The Math class also provides constants such as PI and E which can be used in mathematical calculations.
