How to load LinkedHashMap Values into Hashtable

Question

I have the following code:

clientTableList = new Object[DBQueries.getAllClients().size()][3]; [I want to load 3 records for now]
LinkedHashMap<String, LinkedHashMap<String, String>> ClientHashMap = DBQueries.getAllClients();
System.out.println(clientHashMap.keySet());
//Printing all Values
System.out.println(clientHashMap.values());

Results:

[Bob Hope, Elena Hairr, Blossom Kraatz, Loreen Griepentrog]
[{UserID=2345, GivenName=Bob, FamilyName=Hope, DateOfBirth=August 30, 1963, NameSuffix=Sr, NamePrefix=, [email protected], Phone=519- ... 

I need to load a JTable, my next code is:

for (int i = 0; i < clientHashMap.size(); i++) {
 clientTableList[i] = new Object[] {
 clientHashMap.get("GivenName") + " " + clientHashMap.get("FamilyName"),
 clientHashMap.get("LoginEmail") + " ",
 clientHashMap.get("Phone") + " " 
 };

But I'm getting all null for my clientTableList.

I need to load all values into a HashTable then load the HashTable into clientTableList. Right?

Answer 1

Your clientTableList doesn't have those fields, only its values have them:

int i = 0;
for (Map<String, String> client: clientHashMap.values()) {
 clientTableList[i++] = String.format("%s %s %s %s",
 client.get("GivenName"),
 client.get("FamilyName"),
 client.get("LoginEmail"),
 client.get("Phone"));
};

Following changes worked:

clientTableList[i++] = new Object[]{ client.get("GivenName") + " " + client.get("FamilyName") , client.get("LoginEmail") + " " , client.get("Phone") + " " };
