Math Class

The Math class provides methods for performing mathematical operations like exponentiation, logarithms, square roots, trigonometry, and random generation.

• You don’t need to create an object of the Math class to use its methods.

Key Features:

• All methods are static and can be accessed using Math.methodName().
• It is used for basic and advanced mathematical operations.
• It includes built-in constants for π (pi) and Euler’s number (e).
• It is designed for double precision calculations.
• It is useful in game development, scientific applications, finance calculations, etc.

Math Class Syntax:

• The Math class is a part of the java.lang package.

Math.methodName(arguments);

• final: Cannot be subclassed.
• extends Object: Like all Java classes, it inherits from Object.
• All methods in the Math class are static, so they can be called without creating an object.

Commonly Used Methods:

Random Number Generation:

• Math.random() generates a double value greater than or equal to 0.0 and less than 1.0.

Example:

public class MathClassExample {
    public static void main(String[] args) {
        System.out.println("Square root of 16: " + Math.sqrt(16));
        System.out.println("2 raised to 3: " + Math.pow(2, 3));
        System.out.println("Absolute value of -10: " + Math.abs(-10));
        System.out.println("Round 5.6: " + Math.round(5.6));
        System.out.println("Ceil of 4.3: " + Math.ceil(4.3));
        System.out.println("Floor of 4.7: " + Math.floor(4.7));
        System.out.println("Maximum of 10 and 20: " + Math.max(10, 20));
        System.out.println("Random number: " + Math.random());
    }
