Java代码：将多层嵌套Map转换为List<ComputeResultExportDTO>

To fix this error, you need to define empNameAndCode or provide its value before using it in the code.\n\nHere's an example of how empNameAndCode can be defined and used in the code:\n\njava\n// Assuming empNameAndCode is a Map<String, String> containing employee names and codes\nMap<String, String> empNameAndCode = new HashMap<>();\n empNameAndCode.put("John", "1001");\n empNameAndCode.put("Jane", "1002");\n\nfinal Map<String, Map<String, Map<String, BigDecimal>>> levelSubtotalDict = new HashMap<>();\n\nreturn levelSubtotalDict.entrySet().stream()\n .collect(Collectors.toMap(\n Map.Entry::getKey,\n entry -> entry.getValue().entrySet().stream()\n .map(levelEntry -> {\n String levelName = levelEntry.getKey();\n Map<String, BigDecimal> scoreMap = levelEntry.getValue();\n List<ComputeResultExportDTO> resultList = scoreMap.entrySet().stream()\n .map(scoreEntry -> {\n String assessScore = scoreEntry.getKey();\n BigDecimal totalScore = scoreEntry.getValue();\n ComputeResultExportDTO computeResultExportDTO = new ComputeResultExportDTO();\n computeResultExportDTO.setEmpCode(empNameAndCode.get("John")); // Example of getting empCode from empNameAndCode\n computeResultExportDTO.setEmpName(empNameAndCode.get("John")); // Example of getting empName from empNameAndCode\n computeResultExportDTO.setLevelName("级别小计");\n computeResultExportDTO.setLevelGroup(levelName);\n computeResultExportDTO.setAssessScore(new BigDecimal(assessScore));\n computeResultExportDTO.setTotalScore(totalScore);\n return computeResultExportDTO;\n })\n .collect(Collectors.toList());\n return new AbstractMap.SimpleEntry<>(levelName, resultList);\n })\n .collect(Collectors.toMap(\n Map.Entry::getKey,\n Map.Entry::getValue\n ))\n ));\n\n\nPlease note that you need to modify the code according to the actual implementation and data structures you are using.
