Bank Queue Management System

Question

Hello folks I need a help I am learning to program now, I am developing a password system for waiting queue type JAVA database database.

Password Normal; Password Priority;

Call in Password Reclaim Password

Display (Form for Password)

Follow my class Password

package Modelo;


public class Senha {

private int senha;
private Boolean chamada;
private DateTime inicioAtendimento;
private  Boolean prioritaria;


    public int getSenha() {
        return senha;
    }


    public void setSenha(int senha) {
        this.senha = senha;
    }


    public Boolean getChamada() {
        return chamada;
    }

    public void setChamada(Boolean chamada) {
        this.chamada = chamada;
    }


    public DateTime getInicioAtendimento() {
        return inicioAtendimento;
    }


    public void setInicioAtendimento(DateTime inicioAtendimento) {
        this.inicioAtendimento = inicioAtendimento;
    }


    public Boolean getPrioritaria() {
        return prioritaria;
    }


    public void setPrioritaria(Boolean prioritaria) {
        this.prioritaria = prioritaria;
    }
    }

Class Generate Password

My Button Call Password

private void btChamarActionPerformed(java.awt.event.ActionEvent evt) {                                         
        // TODO add your handling code here:

            senha  novo = new senha();
            novo.GeraSenha();
            label1.Text = "Atendimento Prioritário";
            label2.Text =" Senha: " +novo.GeraSenha();
        }

My doubt is whether I am walking well and what are the classes I should use for this purpose

I’d appreciate the help I’m doing this project for University.
