The Java Math Library provides various Functions and Constants / Properties. These math functions allow us to perform basic mathematical operations like square root, cube root, logarithmic, and trigonometric functions.
Unlike other global objects, Properties and Functions inside the Java math library class are static. So, we can access the properties as Math.PI and functions as Math.abs(number).
