I am going to explain how to import math class in java. So in order to use mathematical functions in a program, we use Math class. This Math class is defined in java.lang package. Math class contains a number of methods for performing various operations like elementary exponential, logarithm, square root and trigonometric, ceil, floor, round etc.
For printing these values and to use methods of Math module we can use static import , which will allow us to access values and methods without writing ‘Math.’ in front of anything . Import statement is look like below : import static java.lang.Math.*. Now let’s print both of these constants :
