推荐答案

如果不使用任何对象将数据存储在表中，则只需在表上逐行遍历并获取每个对象并将其存储在列表中

If you are storing the data in the table with out using any object then just traverse row by row on the table and get every object and store it in the List.

示例:这是当您使用列表存储数据时.

Example: This is when you are using a list to store the data.

List<Object> list = new ArrayList<Object>;

for(int row = 0; row < table.getRowCount(); row++) {
    for(int column = 0; column = table.getColumnCount(); column++) {
      list.add(table.getValueAt(row, column));  
    }
}

最后，您将获得列表中的所有对象.

Finally you will get all the objects in the list.

由于每一行都是CustomObject类型的对象，我们需要将表的每个值设置为CustomObject类型的对象，并将其添加到每一行的列表中.

Since each row is an object of type CustomObject we need to set each value of the table to the object of type CustomObject and add it to the List for every row.

class CustomObject {
   Object one;
   Object two;
}

List<CustomObject> list = new ArrayList<CustomObject>;

for(int row = 0; row < table.getRowCount(); row++) {
  CustomObject object = new CustomObject();
    for(int column = 0; column = table.getColumnCount(); column++) {
       switch(column) {
            case 0:
                  object.setOne(table.getValueAt(row, column));
                  break;
             case 1: 
                  object.setTwo(table.getValueAt(row, column));
                  break;
       }
    }
    // Store each object in the list.
    list.add(object);
}
