Java problem 4.6

6 (Random points on a circle) Write a program that generates three random points on a circle centered at (0,0) with radius 40 and displays three angles in a triangle formed by these three points, as shown in Figure 4.4a. (Hint: Generate a random angle in radians between 0 and 2, as shown in Figure 4.4b and the point determined by this angle is (rxcos(),rxsin()).) x=rcos() and y=rsin()
