I am having problems getting this code to work.

Question

public class Polar {
     public static void main(String[] args) {
          int angle;
          int distance;
          int x1;
          int y1;
     public Polar (int angle, int distance, int x1, int y1) {
          this.angle = angle;
          this.distance = distance;
          this.x1 = x1;
          this.y1 = y1;
     public void printIt() {
          System.out.println(" Angle " + this.angle);
     //int new x1() {
     //     return 1;
this part below, the instructor couldn't get to work and he was going to try to figure out what was wrong.
     /*public int newX(int angle; int distance; int x1; int y1) {
          return (int) (distance * Math.cos(toRadians(angle)));
     public int newY(int angle; int distance; int x1; int y1) {
          return (int) (distance * Math.cos(toRadians(angle)));
I'm getting the error messages that it can't find the symbol variable for angle, distance, x1 and y1 on lines 13 thru 19. I also have to figure out a loop to make it do points 10 times.
Can anyone help me figure out what I'm doing wrong?
TIA

return (int) (distance * Math.cos(toRadians(angle)));Oh, that's because you've put all those variables in your main method, rather than as fields of the class, which is what you meant to do. Compilers never lie!
