How to send data to a discord webhook in java using a single .java file?

I'm working on a Minecraft mod that requires sending a string of data to a discord webhook. What would the most efficient way to achieve this using a singular .java file?

You can use this which personally works for me. This is the full code if the gist expire:

To use it, you have to do something like that:
DiscordWebhook webhook = new DiscordWebhook("https://discordapp.com/api/webhooks/...");
webhook.setContent("Any message!");
webhook.setAvatarUrl("https://your.awesome/image.png");
webhook.setUsername("Custom Usernames!");
webhook.setTts(true);
webhook.addEmbed(new DiscordWebhook.EmbedObject()
.setTitle("Title")
.setDescription("This is a description")
.setColor(Color.RED)
.addField("1st Field", "Inline", true)
.addField("2nd Field", "Inline", true)
.addField("3rd Field", "No-Inline", false)
.setThumbnail("https://kryptongta.com/images/kryptonlogo.png")
.setFooter("Footer text", "https://kryptongta.com/images/kryptonlogodark.png")
.setImage("https://kryptongta.com/images/kryptontitle2.png")
.setAuthor("Author Name", "https://kryptongta.com", "https://kryptongta.com/images/kryptonlogowide.png")
.setUrl("https://kryptongta.com"));
webhook.addEmbed(new DiscordWebhook.EmbedObject()
.setDescription("Just another added embed object!"));
webhook.execute(); //Handle exception

Age filter in Java with ArrayList

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.
package com.company;
public class Contato {
public String nome;
public int idade;
public String sexo;
public String profissao;
public String telefone;
public String email;
public Contato(String nome, int idade, String sexo, String profissao, String telefone, String email) {
this.nome = nome;
this.idade = idade;
this.sexo = sexo;
this.profissao = profissao;
this.telefone = telefone;
this.email = email;
}
#Override
public String toString() {
return "" +
nome + ',' +
idade + " anos de idade, " +
"do sexo " + sexo + ',' +
profissao + ',' +
" telefone nº " + telefone + ", " +
"e-mail:" + email;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public int getIdade() {
return idade;
}
public void setIdade(int idade) {
this.idade = idade;
}
public String getSexo() {
return sexo;
}
public void setSexo(String sexo) {
this.sexo = sexo;
}
public String getProfissao() {
return profissao;
}
public void setProfissao(String profissao) {
this.profissao = profissao;

package com.company;

import java.util.ArrayList;
public class GestaoContatos extends Contato {
ArrayList<Contato> Familia = new ArrayList();
ArrayList<Contato> Amigos = new ArrayList();
ArrayList<Contato> Profissional = new ArrayList();
public GestaoContatos(Contato c) {
super(c.nome, c.idade, c.sexo, c.profissao, c.telefone, c.email);

Amigos = amigos;
}
public ArrayList<Contato> getProfissional() {
return Profissional;
}
public void setProfissional(ArrayList<Contato> profissional) {
Profissional = profissional;
}
}

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();
}

Authentication code Java

after some research and help from a friend I could make a method (authentificate) that compare the username and password given by the user in the Main and the ones presents in the loginList. The problems is the methode always return false, and I can't find the problem.
Thanks in advance for your help.
Main
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String username;
String password;
System.out.println("Enter your username");
username = input.nextLine();
System.out.println("Enter your password");
password = input.nextLine();
UserList test2 = new UserList();
if (test2.authenticate(username, password) == true) {
System.out.println("Hi");
} else {
System.out.println("Username or/and password are wrong.");
}
}
}
User
public class User {
protected String username;
protected String password;
public User(String username, String password) {
this.password = password;
this.username = username;
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
#Override
public boolean equals(Object o) {
if (o instanceof User) {
return ((User) o).username.equals(username);
}
return false;
}
#Override
public int hashCode() {
int hash = 7;
hash = 97 * hash + Objects.hashCode(this.username);
return hash;
}
}
UserList
public class UserList {
private HashSet<User> loginList;emphasized text
public UserList() {
Scanner scan;
loginList = new HashSet();
try {
scan = new Scanner(new File("src/boitedejeux/Logins.txt"));
String ligne = scan.nextLine();
while (scan.hasNext()) {
ligne = scan.nextLine();
String[] res = ligne.split(",");
loginList.add(new User(res[0], (res[1])));
}
} catch (FileNotFoundException e) {
System.out.println("Erreur");
}
}
public boolean authenticate(String username, String password) {
if (null == loginList) {
throw new IllegalStateException("The user list isn't initialised");
}
return loginList.stream()
.filter(usern -> usern.getUsername().equals(username))
.filter(passw -> passw.getPassword().equals(password))
.findFirst()
.isPresent();
}
}
Login.txt
Test, Password
Test2, Password2

Remove spaces after commas in your txt, or change the line of String[] res = ligne.split(",") to split with spaces String[] res = ligne.split(", ").

Expected BEGIN_OBJECT but was STRING at line 1 column 1 GSON

I am getting this error when querying a URL and get a json object. My json:
{"status":1,"username":"admin","nombre":"Username","email":"example#example.cl","codigo_usuario":"1","hash":"2938632bfdklsngh","imagen":"05c151584cc1e9aa2985b5bd0a3a4cd2.jpeg"}
Create the User class
public class User {
private int status;
private String username;
private String nombre;
private String email;
private String codigo_usuario;
private String hash;
private String imagen;
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getNombre() {
return nombre;
}
public void setNombre(String nombre) {
this.nombre = nombre;
}
public String getHash() {
return hash;
}
public void setHash(String hash) {
this.hash = hash;
}
public String getImagen() {
return imagen;
}
public void setImagen(String imagen) {
this.imagen = imagen;
}
public String getCodigo_usuario() {
return codigo_usuario;
}
public void setCodigo_usuario(String codigo_usuario) {
this.codigo_usuario = codigo_usuario;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Override
public String toString() {
return "User [status=" + status + ", username=" + username
+ ", nombre=" + nombre + ", email=" + email
+ ", codigo_usuario=" + codigo_usuario + ", hash=" + hash
+ ", imagen=" + imagen + "]";
}
}
And in my class, I make the request to the URL I have this code:
public static boolean authenticate(String username, String password){
boolean error = false;
User user = null;
try {
String request = Config.getText("URL_BASE")+Config.getText("URL_AUTHENTICATE")+username+"/"+password;
HttpURLConnection conn = (HttpURLConnection) new URL(request).openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Accept", "application/json");
if (conn.getResponseCode() != 200) {
throw new Exception("Failed : HTTP error code : " + conn.getResponseCode());
}
user = new Gson().fromJson(new InputStreamReader(conn.getInputStream()), User.class);
System.out.println(user.toString());
conn.disconnect();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return error;
}
And I get the exception. I saw other post with this same error and in most the error was the json format or class that did not have the same fields. Now, check well and everything should be OK. But for some reason I receive this error
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1

I'm new to Java and try to consume a web service for data and use. I think this is my best option but still do not understand the error.

java.lang.NullPointerException when populating Jtextfield using a bean class

Here is my class which is a gui consisting of two tabs, my profile and edit profile. I am having a problem at the 'myProfileTabStateChanged' method when the index value changes to 1. When tab index is 0, 'myProfile()' method executes successfully, but when index is 1, 'editProfile()' is giving too many errors. The purpose of editprofile() is simply to extract the values from a bean class and set it to the textfields appropriately. What am I doing wrong? Please note the bean class variables are being populated correctly using setter methods, but in this class I am unable to retrieve the values using the getters? Perhaps it is retrieving but problem lies in being unable to set it to textfield.

Just a wild a***'d guess: You appear to have at least two completely unrelated academicBean objects (note that the class should be named AcademicBean), one in Academic, and one in MainMenu. I have a suspicion that they should be one and the same.
Perhaps MainMenu should have:
academicBean bn = ac.getAcademicBean();
and Academic have:
public academicBean getAcademicBean() {
return bean;
}
so that MainMenu can extract Academic's bean making the bean variables refer to one and the same bean object.
