How to enter a date using Calendar?

I need to enter a date that has day, month and year, by keyboard, using the class Calendar, which method I call, of this class.

This is the code:

package models;
import java.util.Calendar;

public class User{
    protected EnumGenderUser gender;
    protected Calendar birthDate;
    protected String password;
    protected EnumCountry country;
    protected String email;

public User (EnumGenderUser gender, Calendar birthDate, String password, EnumCountry country, String email){
    this.setGender(gender);
    this.setBirthDate(birthDate);
    this.setPassword(password);
    this.setCountry(country);
    this.setEmail(email);
}

@Override
public String toString(){
    return super.toString();
}


//--------------------------------Setters------------------------------------------

public void setGender(EnumGenderUser gender){
    this.gender = gender;
}
public void setBirthDate(Calendar birthDate){
    this.birthDate = birthDate;
}
public void setPassword(String password){
    this.password = password;
}
public void setCountry(EnumCountry country){
    this.country = country;
}
public void setEmail(String email){
    this.email = email;
}
//--------------------------------Getters------------------------------------------

public EnumGenderUser getGender(){
    return this.gender;
}
public Calendar getBirthDate(){
    return this.birthDate;
}
public String getPassword(){
    return this.password;
}
public EnumCountry getCountry(){
    return this.country;
}
public String getEmail(){
    return this.email;
}
}

Here the class Daughter:

 package models;
 import java.util.Calendar;

public class Admin extends User{
private String name;
private String occupation;
private int id;

public Admin(String name, String occupation, int id, EnumGenderUser gender, Calendar birthDate, String password, EnumCountry country, String email){
    super(gender, birthDate, password, country, email);
    this.setName(name);
    this.setOccupation(occupation);
    this.setId(id);
}
@Override
public String toString(){
    String formatLine = "%1$-20s %2$-15s %3$-10s %4$-9s %5$-9s %6$-10s %7$-10s %8-30s";
    String adminLine = String.format(formatLine, name, occupation, id, gender, birthDate, password, country, email);
    return adminLine;
}
//--------------------------------Setters------------------------------------------

public void setName(String name){
    this.name = name;
}
public void setOccupation(String occupation){
    this.occupation = occupation;
}
public void setId(int id){
    this.id = id;
}
//--------------------------------Getters------------------------------------------

public String getName(){
    return this.name;
}
public String getOccupation(){
    return this.occupation;
}
public int getId(){
    return this.id;
}
}

The Enumerated:     package models;

public enum EnumGenderUser{
FEMENINO, MASCULINO;
}
package models;
public enum EnumCountry{
COLOMBIA, VENEZUELA, ARGENINA, CHILE, ECUADOR;
}

and the test:

package test;
import models.Admin;
import models.EnumCountry;
import models.EnumGenderUser;
import java.util.Calendar;

public class TestModels{

public static void main(String[] args){
    Admin adminObj = new Admin("Juan", "Diseñador", 64335, EnumGenderUser.MASCULINO, calendar.set(1990, 04, 12), "Qwerty123", EnumCountry.COLOMBIA, "[email protected]");
    System.out.println(adminObj.toString());
}

}
