我正在尝试将这些值分组到如下地图中：
private static Map showExcelData(List sheetData) {
String tempEmpid="",strdepartment="";
int j=1;
Map employeeMap = new LinkedHashMap();
Map tempEmployeeMap = new LinkedHashMap();
for (int i = 0; i < sheetData.size(); i++) {
List list = (List) sheetData.get(i);
HSSFCell employeeid = (HSSFCell) list.get(0);
HSSFCell department = (HSSFCell) list.get(3);
HSSFCell date = (HSSFCell) list.get(5);
strdepartment = department.getRichStringCellValue().getString();
if(!(employeeid.getRichStringCellValue().getString().equals("EmpID") || date.getRichStringCellValue().getString().equals("Date") || department.getRichStringCellValue().getString().equals("Department"))){
if(!(strdepartment.equals("Temporary Card") || strdepartment.equals("Contractor"))){
employeeMap.put(employeeid.getRichStringCellValue().getString()+"_"+j,date.getRichStringCellValue().getString());
j++;
}
}// System.out.println("");
}
return employeeMap;
}
我认为在这里我可以根据员工 ID 对值进行分组，但坦率地说，我不知道该怎么做，因为我是 Java 中的新人。
所以我尝试从上述方法获取地图并尝试如下处理
employeeMap = showExcelData(sheetData);
String previousEemployeeID = "",employeeID[];
Iterator<Map.Entry> entries = employeeMap.entrySet().iterator();
int i=0;
while (entries.hasNext()) {
Map.Entry entry = entries.next();
employeeID = entry.getKey().toString().split("_");
System.out.println("employeeid : "+employeeID[0]);
if(previousEemployeeID.equals(employeeID[0])){
System.out.println(" If Key = " + entry.getKey() + ", Value = " + entry.getValue()+" : possible key is : "+employeeID[0]+"_"+String.valueOf(i));
i++;
}else{
if(i==0) System.out.println("previousEmployee id : "+entry.getKey());
System.out.println("Else Key = " + entry.getKey() + ", Value = " + entry.getValue()+" : possible key is : "+employeeID[0]+"_"+String.valueOf(i));
i=0;
}
previousEemployeeID = employeeID[0];
}
在这里，我只想根据员工 id 对值进行分组，但实际上得到的答案很糟糕，如果我尝试在 map 的第一个元素上方被消除，而第二个元素的结果很好。
这是完整的代码：

所以请帮我做以下事情：
- 根据员工 ID 对值进行分组。
