And at any point the system can be asked how many entities are in-progress (or in-flight). The system is expected to give this count, as fast as possible  \n\n- [Pendency System - Complete Problem Statement](https://github.com/alpha74/PendencySystem_JavaSpringBoot/blob/main/docs/problem_statement.md)\n\n\n```\nThis is not the Code in actual interview.\nDone as a practice for this problem statement.\nHence, design is done more thoughtfully.\n```\n\n\n### Code/Run\n\n- Java8, Maven, IntelliJ(Community)\n\n- Driver class `TrackingServiceTest.java`\n- All necessary code in `src` dir\n\n\n### Understanding the Working\n\n- To understand the working, read Problem Statement thoroughly\n- Then explore `dir` in this order:\n  1. Entities\n  2. Repository\n  3. `TrackingServiceTest.java`\n  4. Then, deeply go through Services\n  \n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falpha74%2Fpendencysystem_javaspringboot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Falpha74%2Fpendencysystem_javaspringboot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falpha74%2Fpendencysystem_javaspringboot/lists"}
