得到一个输出为 [Ljava.lang.Object;@1d4481 [重复]

Question

我正在尝试将一组月份和日期打印到表格的列中。它显示 {Ljava.lang.Object;@1d4481 错误..但是当我尝试将天数打印到行时它工作正常..我搜索了stackover线程，也发现了类似的问题，它说对象类型的东西.. 这是我的表格属性

这是我的代码

    Calendar calendar = Calendar.getInstance();
    //System.out.println("The current date is : " + calendar.getTime());
    System.out.println("The current date is : " + calendar.getTime()); 

    calendar.set(1995, 10, 2);
    for(int i=0; i<2 ; i=i+1){
    calendar.add(Calendar.DATE, 1);
    //System.out.println(" Dates later: " + calendar.getTime());
    System.out.println(" Dates later: " + calendar.get(Calendar.MONTH)+"/"+calendar.get(Calendar.DATE));

    //System.out.println(" Dates later: " + Arrays.toString(calendar.get(Calendar.MONTH).toArray())+"/"+Arrays.toString(calendar.get(Calendar.DATE).toArray()));


    SimpleDateFormat dFormat = new SimpleDateFormat("yyyy-MM-dd");
    String date = dFormat.format(jDateChooser1.getDate()); 
    DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
    //model.addRow(new Object[]{calendar});

     //model.addRow(new Object[]{calendar.get(Calendar.MONTH)+"/"+calendar.get(Calendar.DATE)});  
     model.addColumn(new Object[]{calendar.get(Calendar.MONTH)+"/"+calendar.get(Calendar.DATE)});
    }

你可以尝试把这样的一行：model.addRow();并通过此方法传递具有所有列值的字符串数组。
