合同开始日期：2023-01-01，结束日期：2026-01-01，免租起始期：2023-01-01，免租终止日期：023-01-31，不足月按月算，计费面积：100平方米，月租单价20/平方米，计算方式：每3月计算产生一条记录，收款方式为按3个月收一次，提前收款期为1个月，基本租期12月，超过基本租期后按12月为一个递增周期，每一递增周期内月租单价按上一周期内月租单价复合递增，年递增率为6%；按java7的语法：按计算方式循环产生合同期内含收款日期、租期起始日期、租期终止日期、租期单价、租期（月数）、租金的计划列表，生成一个完整示例和测试方法

好的，根据您的需求，我已经编写了一个示例和测试方法，如下所示：

这个代码生成了一个租赁合同的计划列表，包括每次收款的日期、租期起始日期、租期终止日期、租期单价、租期（月数）和租金。您可以在`main`方法中直接运行测试，输出的结果将显示在控制台上。
