Java Code:
public class MathTest {
  public static void main(String args[]) {
    int angles[] = { 0, 30, 45, 60, 90, 180 };
    for (int i = 0, n = angles.length; i < n; i++) {
      double rad = Math.toRadians(angles[i]);
      System.out.println("Angle: " + angles[i]);
      System.out.println(" Sine  : " + Math.sin(rad));
      System.out.println(" Cosine : " + Math.cos(rad));
      System.out.println(" Tangent: " + Math.tan(rad));
    }
  }
}
