The Java Math Library provides various Functions and Constants / Properties, which allows us to perform basic mathematical functionality such as the elementary exponential, square root, cube root, logarithmic and trigonometric functions.

Unlike other global objects, Properties and Functions inside the Java math class are static. So, we can access the properties as ** Math.PI** and functions as

*.*
