+/*	Write a Java program to read the radius of a circle as an integer from the user. Calculate the diameter, circumference and area of the circle using the floating-point value of π = 3.14159. You can also use the value of π from the Math class which is available in java.lang.
+Diameter = 2r
+Circumference = 2 πr
+Area = πr2
