文件输入问题

程序：....
ArrayList<Region > region=new ArrayList<Region >();
Scanner rin=new Scanner(new File("E:\\MapZhou\\Region1.mif"));
for(int r=0;r<7;r++){
rin.nextLine();//跳过文件头的7行
}
while(rin.hasNext()){
Region rr=new Region();
rin.nextLine();

int rlength=Integer.parseInt(rin.next());//获取循环的上限
for(int r1=0;r1<rlength;r1++){
Point rp=new Point();
rp.setX_point(Double.parseDouble(rin.next()));
rp.setY_Point(Double.parseDouble(rin.next()));
rr.setPoint(rp);

}
rin.nextLine();
region.add(rr);
}
......
