I got this error: "Type mismatch: cannot convert from element type Object to List" in "subLists" "and Type mismatch: cannot convert from element type Object to String" in "accList"
Code:
ArrayList subLists = new ArrayList();
for (List accList : subLists) {
service.submit(() -> {
for (String account : accList) {
accounts.remove(account);
String[] split = account.split(":");
String email = split[0];
String password = split[1];
AuthResult result = null;
You did not specify what type of object was in the different lists, you need to, the programm won't guess :
List<List<String>> subLists = new ArrayList<>();
for (List<String> accList : subLists) {
service.submit(() -> {
for (String account : accList) {
// ...
Also, better use Interfaces than Implementations to store the variable, easier to update (List<List<String>> rather than ArrayList<List<String>>
