问题描述：

Exceptioninthread"main"java.lang.ArrayIndexOutOfBoundsException:0atPoint.main(Point.java:15)

publicclasspoints{

protectedintx,y;

publicpoints(){setPoint(0,0);}

publicpoints(inta,intb){setPoint(a,b);}

publicvoidsetPoint(inta,intb){

x=a;

y=b;

}

publicintgetX(){returnx;}

publicintgetY(){returny;}

publicStringtoString()

{return"["+x+","+y+"]";}

}

但是运行的时候不对……就是一行上面的字
