Write a java program to display three image in the same window. I have written the codes for the image but do not know how to write the main method to display all three images at the same time at runtime. I am also unsure what to import at the beginning of the codes that would work. This is the images that need to be display:

public class ClockPane extends Pane { private int hour; private int minute; private int second; private boolean hourHandVisible; private boolean minuteHandVisible; private boolean secondHandVisible;

/** Construct a default clock with the current time */ public ClockPane() { setCurrentTime(); }

/** Return hour */ public int getHour() { return hour; }

/** Set a new hour */ public void setHour(int hour) { this.hour = hour; paintClock(); }

/** Return minute */ public int getMinute() { return minute; }

/** Set a new minute */ public void setMinute(int minute) { this.minute = minute; paintClock(); }

/** Return second */ public int getSecond() { return second; }

/** Set a new second */ public void setSecond(int second) { this.second = second; paintClock(); }

/** Return clock pane's width */ public double getW() { return w; }

/** Set clock pane's width */ public void getW(double w) { this.w = w; paintClock(); }

getChildren().clear(); getChildren().addAll(circle, t1, t2, t3, t4); if (secondHandVisible) getChildren().add(sLine); if (minuteHandVisible) getChildren().add(mLine); if (hourHandVisible) getChildren().add(hLine); } }
