Given this Star class:

public class Star { private double x,y; private String name; private double brightness; public Star() { name=""; } public Star(String s) { name = s; } public Star(String s, double b) { name = s; brightness = b; } public Star(String s, double x1, double y1) { name = s; x = x1; y = y1; } public Star(String s, double b, double x1, double y1) { name = s; x = x1; y = y1; brightness = b; } public double getX() { return x; } public void setX(double x) { this.x = x; } public double getY() { return y; } public void setY(double y) { this.y = y; } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getBrightness() { return brightness; } public void setBrightness(double brightness) { this.brightness = brightness; } }

How many constructors methods are there?
