Develop a Java program to compute and report the area and the circumference of a circle, given its radius. Have the user enter a value for RADIUS, a positive double value. Then using the value of 3.14 as PI (set up as a named constant), calculate and display the circle's area (PI times RADIUS times RADIUS) and the circumference (2 times PI times RADIUS). As long as the entered value for RADIUS is non-positive, then have the user try again.  Once a valid value for RADIUS is entered, then continue with the above computations and reporting.
