    protected void service(HttpServletRequest request, HttpServletResponse response)   
            throws IOException, ServletException { 


 PrintWriter out = response.getWriter();

 ...

    StringBuilder finalDate = new StringBuilder("DataNascimento1")
.append("/"+request.getParameter("DataNascimento‌​2"))
.append("/"+request.getParameter("DataNascimento3"));

 try {  
     Date date = new SimpleDateFormat("dd/MM/yyyy"); //here there are error 
     finalDate.toString(); 

 } catch(ParseException e) {  
     out.println("Erro de conversão da data");  
     return;   
 } 
 Contato contato = new Contato();  
     ??????????

我的物道

    package br.com.cad.dao;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Date;

import br.com.cad.dao.ConnectDb;

public class Cadastro {  

    private Connection connection;  


    public Cadastro() {  
        this.connection = new ConnectDb().getConnection();  
    }  

    public void adiciona(Contato contato) {  
        String sql = "INSERT INTO dados_cadastro(pf_nome, pf_ultimonome, pf_rg, pf_cpf, pf_sexo,pf_dt_nasc) VALUES(?,?,?,?,?,?,?,?)";  
        try {  

            PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setDate(6, new Date( contato.getDataNascimento1().getTimeInMillis()) );
stmt.execute();  
            stmt.close();  
            System.out.println("Cadastro realizado com sucesso!.");  
        } catch(SQLException sqlException) {  
            throw new RuntimeException(sqlException);  
        }  
    }

我的班级简介

package br.com.cad.basica;

导入 java.util.Calendar；

公共类Contato {

    private Long id;
    private String nome;
    private String sobrenome;
    private String email;
    private String endereco;
    private Calendar dataNascimento1;
    private Calendar dataNascimento2;
    private Calendar dataNascimento3;
    private String rg;
    private String cpf;
    private String sexo;
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getNome() {
        return nome;
    }
    public void setNome(String nome) {
        this.nome = nome;
    }
    public String getSobrenome() {
        return sobrenome;
    }


... getters and setters...

请帮助我找出我的代码中的一些错误并实现它以将数据保存在我的数据库中......

您应该将值传递为 01, 02, 03 而不是 1, 2, 3 （对于天和月）。检查您的 Web 表单和日期选择值。

Date date = new SimpleDateFormat("dd/MM/yyyy"); //here there are error

这是错误的声明。

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");

这不会引起问题。
