java编写一个light类，包含两个成员变量，两个构造器方法，三个成员方法

public class Light {
private boolean isOn;
private String color;

public Light() {
this(false, "white");
}

public Light(boolean isOn, String color) {
this.isOn = isOn;
this.color = color;
}

public void turnOn() {
this.isOn = true;
}

public void turnOff() {
this.isOn = false;
}

public void setColor(String color) {
this.color = color;
}

public boolean isOn() {
return isOn;
}

public String getColor() {
return color;
