Please help me with my projectiles and angles program!!!!

Question

I am having problems lining things up correctly. my program generates a table telling you how far an object will travel based upon its angle and its velocity. the chart has the angles along the top and the velocites down the side. default angles are 10,20,30,40,50,60,70,80 and default velocities are 20,40,60,80,100. I need the user to be able to enter the smallest angle, the angle increment, and the total number of angles.
My problem is for exmaple if i enter the smallest angle as 20, increment as 5, and total number as 4 it will display the correct calculations but the angles on the top will not line up. It will display angles 0,5,10,15 when its suppose to be showing 20,25,30,35. Anyone know how to fix this?
Also i need the user to be able to enter the minimum initial velocity, maximum initial velocity, and the number of equally spaced initial velocities. for example if the user enter smallest velocity 10, largest velocity 30, and total number 5 it should display the distances for initial velocities 10,15,20,25,30. Any ideas on that one? I will post my code below. Thanks again for any help you can provide!!
import java.util.*;
public class test
/** Main Method**/
     public static void main(String[] args)
          Scanner sc = new Scanner(System.in);
          int smallestAngle, increment, totalAngles,angleDegree = 0, velocity = 0;
          double answer = 0;
          System.out.print("Please enter the smallest angle: ");
          smallestAngle = sc.nextInt();
          System.out.print("Please enter the increment: ");
          increment = sc.nextInt();
          System.out.print("Please enter the total number of angles: ");
          totalAngles = sc.nextInt();
          for(int i = 0; i < totalAngles; i++)
               System.out.print("\t" + (angleDegree + (increment * i)));
          for(int i = 0; i < (totalAngles * 5); i++)
               if((i % totalAngles) == 0)
                    angleDegree = smallestAngle;
                    velocity += 20;
                    System.out.print("\n" + velocity);
               answer = Math.round((Math.pow(velocity, 2) * Math.cos(Math.toRadians(angleDegree)) * Math.sin(Math.toRadians(angleDegree))) / 32);
               System.out.print("\t" + answer);
               angleDegree += increment;
          System.out.println("\n\n");
}

Answer 1

Ok i re wrote my code another way hoping it would help solve things. My prob now is that it will only display the correct degree headings and not produce any form of calculation. I need to find a way for the user to enter the minimum initial velocity they want, the maximum initial velocity they want, and finally the number of equally spaced equally initial velocities. After this I need the program to produce the table with the calcuations. MY CODE SO FAR IS POSTED BELOW!! PLEASE PROVIDE SOME CODE OR INSIGHT TO FIX MY PROBLEM!! :-) THANKS!
