从文件中读取元素，并将其作为对象存储在ArrayList中

    public static void main(String [] args) throws IOException{


    try{
            FileReader a=new FileReader(\"src/SET_A.txt\");
            Scanner b=new Scanner(a);
            ArrayList<Object> c=new ArrayList<Object>();
            while(b.hasNextLine())
                {
                    Object d=b.nextInt();
                    c.add(d);
                 }
            System.out.println(\"The content of arraylist is: \" + a);
    }
    catch(Exception exception)
    {
        exception.printStackTrace();
    }
    }
