In Java 1. Suppose you have a class Circle that represents circles which all have centers at the same point. (To make it concrete, you can take the circles to be in the usual x,y plane and to all have their centers at the origin.) Suppose there is a Boolean valued method inside of the class Circle such that, for circles c1 and c2, c1.inside(c2) returns true if c1 is completely inside of c2 (and c2 is not the same as c1). Is the following a total ordering? c1 comes before c2 if c1 is inside of c2 (that is, if c1.inside(c2) returns true). You could represent objects of the class Circle by a single value of type double that gives the radius of the circle, but the answer does not depend on such details.

Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.
