I can't print all the studients for the course. I need help. Thanks.
Set lines = new HashSet(10000); // maybe should be bigger
String line;
This following line should be changed from
long count = (long) session.createQuery("select count(*) from Cursos where estudianteses="+estu.getEstudianteses()).uniqueResult();
to this
long count = (long) session.createSQlQuery("select count(*) from Cursos where estudianteses="+estu.getEstudianteses()).uniqueResult();
It has to be createSqlQuery()

I want to make a method that tells me who is the oldest person in the ArrayList and who is the youngest person. The method will receive the arraylist that i want to apply the method, i have 3 in my code, each one is an contact list.
The method is suppose to return the name of the person, but i don't know how to do it. Familia, Profissional and Amigos are my arraylists and "idade" = age and "nome" = name.

If you want to return oldest person in one list:
public Contato oldestPerson(String nomeAgenda){
return Familia.stream()
.filter(c -> c.getNome().equals(nomeAgenda)) // contatos named nomeAgenda
.max(Comparator.comparingInt(Contato::getIdade)) // take oldest
.get();
}
For all lists you can do:
public Contato oldestPerson(){
return Stream.of(Familia, Amigos, Profissional)
.flatMap(Collection::stream) // flatting to one long stream
.filter(c -> c.getNome().equals(nomeAgenda)) // contatos named nomeAgenda
.max(Comparator.comparingInt(Contato::getIdade))
.get();
}
EDIT
Based on the comment, we should change a couple of things to achieve what you want. First, we should define a Map<String, List<Contato>> and populate it in the constructor:
private Map<String, List<Contato>> contatoGroups;
private static final String familiaKey = "Familia";
private static final String amogisKey = "Amigos";
private static final String profissionalKey = "Profissional";
public GestaoContatos(Contato c) {
super(c.nome, c.idade, c.sexo, c.profissao, c.telefone, c.email);
contatoGroups.put(familiaKey, new ArrayList<>());
contatoGroups.put(amogisKey, new ArrayList<>());
contatoGroups.put(profissionalKey, new ArrayList<>());
}
(Consider using enum instead of String as key in the map)
Then wherever you want to get a group, for example: Familia, you should do:
List<Contato> contatoes = contatoGroups.get(familiaKey);
And then we should change the oldestPerson() like this:
public Contato oldestPerson(String nomeAgenda){ // nomeAgenda could be "Familia", "Amigos"...
List<Contato> selectedGroup = contatoGroups.get(nomeAgenda);
return selectedGroup.stream()
.max(Comparator.comparingInt(Contato::getIdade)) // take oldest
.get();
}

please help me
This has nothing to do with the problem described by the original poster, but if you got here via Google search, here is something that might be relevant.
I recently updated Room from 2.4.x to 2.5.x and encountered error: incompatible types: <null> cannot be converted to int.
I had to replace androidx.room.OnConflictStrategy.REPLACE with androidx.room.OnConflictStrategy.Companion.REPLACE to fix.
thank you #ianhanniballake. problem solved!.
in CustomerDAO file i found this problem:
#Transaction
#Query("SELECT * FROM Customer")
public List<CustomerOfServiceProvider> getCustomersOfServiceProvider();
type of this list must be ServiceProvidersOfCustomer:
#Transaction
#Query("SELECT * FROM Customer")
public List<ServiceProviderOfCustomer> getServiceProvidersOfCustomer();
Like #solamour I also upgraded to room 2.5.x but my problem was this line:
#ColumnInfo(name = "elapsedTime", typeAffinity = INTEGER, defaultValue = "0")
And I changed it to:
#ColumnInfo(name = "elapsedTime", typeAffinity = ColumnInfo.Companion.INTEGER, defaultValue = "0")
I'm new at this.
I have something like this:
{
libri.get(i).setUtenteAssegnato(**Utente**); How do i create an Utente instance with user inputs?
}
Utente class:
package Biblioteca;
public class Utente
{
private String nome;
private String cognome;
public Utente (String unNome, String unCognome)
{
this.nome=unNome;
this.cognome=unCognome;
}
public String getNome()
{
return nome;
}
public String getCognome()
{
return cognome;
}
public String toString()
{
return (this.nome + this.cognome);
}
}
This is the Libro class, with setUtenteAssegnato method:
package Biblioteca;
public class Libro
{
private int codice;
private String titolo;
private Utente utenteAssegnato;
public Libro (int unCodice, String unTitolo)
{

This is the class i'm having problem with:
package Biblioteca;
import java.util.ArrayList;
import java.util.List;
public class Biblioteca
{
List<Libro> libri = new ArrayList<Libro>();
List<Utente> utenti = new ArrayList<Utente>();
public Biblioteca ()
{
}
public void aggiungiUtente (String unNome, String unCognome)
{
Utente u1 = new Utente (unNome, unCognome);
utenti.add(u1);
}
public void aggiungiLibro(int unCodice, String unTitolo)
{
Libro l1 = new Libro (unCodice, unTitolo);
libri.add(l1);
}
public void creaPrestito (int unCodice, String unCognome)
{
boolean codiceTrovato = false;
boolean cognomeTrovato = false;
int i;
int j;
for (i=0; i<libri.size(); i++)
{
if (libri.get(i).getCodice() == (unCodice))
{
System.out.println("Codice trovato. ");
codiceTrovato = true;
}
else
{
System.out.println("Codice non trovato. ");
}
}
for (j=0; j<utenti.size(); j++)
{
if (utenti.get(j).getCognome().equals(unCognome))
{
System.out.println("Utente trovato. ");
cognomeTrovato = true;
}
else
{
System.out.println("Utente non trovato. ");
}
}
if (codiceTrovato && cognomeTrovato)
{
**libri.get(i).setUtenteAssegnato(Utente);**
}
}
public String toString()
{
String stampa = ", ";
for(Libro d : libri)
{
stampa += d.toString();
}
return stampa;
}
}
Basically, i don't know how to set the object in the arraylist (i) position from input (it should be 2 strings, right?)
Do i have to create another instance of Utente?

I have created table in SQL
I inserted few data
I coded for search city only, where I given mumbai which is already there in database, but result set is not coming
Can you please find the mistake, where I am gone wrong?

First, make sure you have the protocol set for your request.
Second, make sure that the String containing the URL is URL-encoded. I.e. the URL doesn't have any spaces and other special characters - these should be encoded (space is %20 etc).
Given that the two above are met, your program should not throw an exception from the java.net.URL class.
Looking at the exception above, you'll just have to set the protocol (http://), but do make sure that you encode your URL address strings properly or else you'll get exceptions from other parts of your program.
Also, adding http:// to the following string will also result in a MalformedURLException:
"localhost/uatpw/ActiveTransaction"?isx=E13F42EC5E38 as your URL would contain special characters (" in this case) which would need to be encoded.
To provide a valid URL you should make sure that the quotes are stripped from your URL's server and path segments areas:
localhost/uatpw/ActiveTransaction?isx=E13F42EC5E38. Prepeding http:// to this will result in a valid URL.
You are missing the protocol (e.g. http://) in front of localhost.
The welformed URL could be http://localhost/uatpw/ActiveTransaction
This is not a question. What are you trying to do?
But otherwise, "localhost/uatpw/ActiveTransaction" is not a valid URL. An url must start with a protocol (http, https, ftp, etc.).
You should try with:
http://localhost/uatpw/ActiveTransaction
