static double x,y;
public void Point(){
this.x=0.0; this.y=0.0;
}
public double distance(Point that){
double xdiff = this.x-that.x; double ydiff = this.y-that.y;
return Math.sqrt(xdiff*xdiff+ydiff*ydiff);
}
}
class PointSample{
public static void main(String[] args){
Point lowerLeft = new Point(); Point upperRight = new Point();
lowerLeft.x = 0.0; lowerLeft.y = 0.0;
upperRight.x=1280.0; upperRight.y=1024.0;
double d = lowerLeft.distance(upperRight);
System.out.println("Distance = " + d);
}
}
dが0.0になっちゃうんだけどちゃんと出力するにはどうすりゃええんや
