public class SuggestedLevelExportDTO 员工编号。 private String empCode; 员工名称。 private String empName; 部门名称。 private String deptName; 权重组名称。

According to the empWeightLevelGroup map, iterate through its values and count the number of occurrences for each suggestedLevel. Here's an example implementation:

Map<String, Integer> suggestedLevelCounts = new HashMap<>();

for (Map<String, SuggestedLevelExportDTO> levelMap : empWeightLevelGroup.values()) {
    for (SuggestedLevelExportDTO dto : levelMap.values()) {
        String suggestedLevel = dto.getSuggestedLevel();
        suggestedLevelCounts.put(suggestedLevel, suggestedLevelCounts.getOrDefault(suggestedLevel, 0) + 1);
    }
}

// Print the suggestedLevel and its count
for (Map.Entry<String, Integer> entry : suggestedLevelCounts.entrySet()) {
    String suggestedLevel = entry.getKey();
    int count = entry.getValue();
    System.out.println(suggestedLevel + ": " + count);
}

This code calculates the count of each suggestedLevel and stores it in the suggestedLevelCounts map. Then, it loops through the map entries to print the suggestedLevel and its count
