class RandomFile {
    public RandomFile() {
    }
void n(){
    int [] A = {1,2,3,4,5,6,7,8,9,0};
    try{
        RandomAccessFile obj= new RandomAccessFile("rand.dat","rw");
        for (int i=0;i<A.length;i++){
            obj.writeInt(A[i]);
        }
        System.out.println("逆向内容");
        for(int i=A.length-1;i>=0;i--){
            obj.seek(i*4);
            System.out.println(obj.readInt());
        }        obj.close();
    }catch (Exception n){
        System.out.println("发生异常"+n);
    }finally {
        System.out.println("始终在最后执行...");
        System.out.println("在 finally 语句块内");
    }
}
    public static void main(String[] args) {
        RandomFile randomfile = new RandomFile();
        randomfile.n();
    }
}
请问seek()里为什么要乘以4才可以?
seek()的用法?
