Thread: please help

In an orthogonal system, given a point, a line from that point to the origin forms an angle with the positive x-axis. The line is said to terminate, either in one of the four quadrants or to coincide with the positive x-axis, positive y-axis, negative x-axis, or negative y-axis.

Write a java program that prompts the user for a given angle and determines the location of the line, whether it is in one of the four quadrants or it lies on the positive x-axis, positive y-axis, negative x-axis or negative y-axis. For example, if the input angle is 90°, then the line lies on the positive y-axis. If the angle is -30°, then the line lies in the fourth quadrant and so forth. Your program must be able to handle angles of any values, such as -783.87.

i cant think of a way to begin
scanner scan= new scanner (system.in);
i am visualizing the code
but i cant write it
i need to figure out a way to to put in if the multiples of (0,90 180 and 360)
we can use switch but i dont know how
thank u

import java.util.Scanner;
public class Angle
{
public static void main(String []args)
{
double a;
Scanner scan=new Scanner (System.in);
system.out.println("Enter the value for an angle");
a=scan.nextDouble();
if(a>0 && a<90)
system.out.println("The line is located in quadrant 1")
else
if (a==0)
System.out.println("The line is located on positive x-axis")

If i continue in this manner i will finish in a couple of years
how can i condense my code

import java.util.Scanner;
public class Angle {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
double a;
Scanner scan=new Scanner (System.in);
System.out.println("Enter a value for an angle");
a=scan.nextDouble();
if (a>0 && a<90)
System.out.println("The line is located in Quardrant I");
else
if (a>90 && a<180)
System.out.println("The line os located in Quadrant II");
else
if (a>180 && a<270)
System.out.println("The line is located in Quadrant III");
else
if (a>270 && a<360)
System.out.println("The line is located in Quadrant IV");

else
if (a==0)
System.out.println("The line lies on the positive x-axis");
else
if (a==90)
System.out.println("The line lies on the positive y-axis");
else
if (a==180)
System.out.println("The line lies on the negative x-axis");
else
if (a==270)
System.out.println("The line lies on the negative y-axis");




how can i put in the negative value....
ALMOST DONE
