是的

好的，以下是按照您提供的需求编写的Java 7示例代码：

import java.util.ArrayList;
import java.util.List;

    private int increasePeriod;
    private double increaseRate;

    public RentContract(LocalDate startDate, LocalDate endDate, LocalDate rentFreeStartDate, LocalDate rentFreeEndDate, double area, double unitPrice, int basePeriod, int increasePeriod, double increaseRate) {
        this.startDate = startDate;

                records.add(new RentRecord(currentDate, null, null, 0));

            }
        }
        return records;
    }

    public static void main(String[] args) {

                LocalDate.of(2026, 1, 1),
                LocalDate.of(2023, 1, 1),
                LocalDate.of(2023, 1, 31),

class RentRecord {

上面的代码中，`RentContract`类表示租赁合同，包含合同起始日期、合同结束日期、免租起始日期、免租结束日期、计费面积、月租单价、基本租期（月数）、递增周期（月数）和递增率等属性。`calculateRentRecords`方法用于计算合同期内的租金计划列表，返回一个`RentRecord`对象的列表。`RentRecord`类表示租金记录，包含收款日期、租期起始日期、租期终止日期和租金等属性。

在`main`方法中，我们创建了一个租赁合同对象，并调用`calculateRentRecords`方法计算租金计划列表。最后，我们遍历租金计划列表，依次输出每条记录的收款日期、租期起始日期、租期终止日期、租期单价、租期（月数）和租金。

请注意，由于您没有提供具体的计算方式，因此我们在示例代码中采用了一个可能的计算方式，即每3个月计算一次租金并按3个月收一次款。如果您需要更改计算方式，请修改`calculateRentRecords`方法中的代码。
