private String address;
private String sex;
public User(){}

public User(String username, String password, String address, String sex) {
super();
this.username = username;

this.address = address;
this.sex = sex;
}

public String getUsername() {
return username;
}
public void setUsername(String username) {

}
public String getSex() {
return sex;
}
public void setSex(String sex) {

}

public String toString() {
return this.getUsername()+","+this.getPassword()+","+this.getAddress()+","+this.getSex();
}

public List showAllInfo(){
User u=new User("name","upass","hz","male");
List userlist=new ArrayList();
userlist.add(u);
return userlist;
}

public static void main(String[] args) {
