Mathematical Operations in Java Example

Most of the computer languages typically support advanced math operations (such as square root, trigonometric sine, cosine etc.) by way of function libraries. Java also provides a range of methods that support such functions in the standard libraries Math class stored in the package java.lang. Java’s Math class contains a collection of methods and two constants that compute standard mathematical functions.

All the methods and constants available in the Math class are static; so they can simply be referred by just writing class name Math and name of the method or constant you want to use separated by a period (.)

//Program to Show various Methods of Math Class
 public class MathematicalOperations
{
       public static void main(String [] args)
   {
          System.out.println("Absolute value -16 = " + Math.abs(-16));
          System.out.println("Sine of va1ue PI/2= " + Math.sin(Math.PI/2));
          System.out.println("Arc Cosine of -1  = " + Math.acos(-1));
          System.out.println("Upper limit of 7.8 = "+ Math.ceil(7.8));
          System.out.println("Lower limit of 7.8 = "+ Math.floor(7.8));
          System.out.println("Maximum of 15 and 20 = " +Math.max(15,20));
          System.out.println("Rounded value = " + Math.round(7.68));
          System.out.println("Square root of 4 = " + Math.sqrt(4.0));
          System.out.println("2 power 3 is  = " + Math.pow(2.0,3.0));
          System.out.println("Log of 1000 = " + Math.log(1000.0));
