javase：String+正则实现注册功能


使用String工具类实现简单的注册功能，主要包括使用正则表达式判断输入的字符串是否合法，结合异常抛出，完善了注册的功能，使其更加像一个完整项目中的功能
User.java 

package StringRegularExpression;

import java.io.Serializable;
import java.util.Objects;

public class User implements Serializable {

    private int id ;
    private String userName;
    private String password;
    private int age;
    private boolean gender;

    public String getUserName() {
        return userName;
    }

    public boolean isGender() {
        return gender;
    }

    public int getAge() {
        return age;
    }

    public String getPassword() {
        return password;
    }

    public int getId() {
        return id;
    }

    public User(){
        super();
    }

    public User(int id,String userName,String password,int age,boolean gender){
        super();
        this.id = id;
        this.userName = userName;
        this.password = password;
        this.age = age;
        this.gender = gender;

    }

    public void setId(int id){
        this.id = id;
    }

    public void setUserName(String password){
        this.userName = userName;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public void setAge(int age){
        this.age = age;
    }

    public void setGender(boolean gender){
        this.gender = gender;
    }



    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof User)) return false;
        User user = (User) o;
        return id == user.id &&
                age == user.age &&
                gender == user.gender &&
                userName.equals(user.userName) &&
                password.equals(user.password);
    }

    @Override
    public int hashCode() {
        return Objects.hash(id, userName, password, age, gender);
    }


}

UserDemo.java

package StringRegularExpression;

import java.io.Serializable;
import java.util.Objects;

public class User implements Serializable {

    private int id ;
    private String userName;
    private String password;
    private int age;
    private boolean gender;

    public String getUserName() {
        return userName;
    }

    public boolean isGender() {
        return gender;
    }

    public int getAge() {
        return age;
    }

    public String getPassword() {
        return password;
    }

    public int getId() {
        return id;
    }

    public User(){
        super();
    }

    public User(int id,String userName,String password,int age,boolean gender){
        super();
        this.id = id;
        this.userName = userName;
        this.password = password;
        this.age = age;
        this.gender = gender;

    }

    public void setId(int id){
        this.id = id;
    }

    public void setUserName(String password){
        this.userName = userName;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public void setAge(int age){
        this.age = age;
    }

    public void setGender(boolean gender){
        this.gender = gender;
    }



    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof User)) return false;
        User user = (User) o;
        return id == user.id &&
                age == user.age &&
                gender == user.gender &&
                userName.equals(user.userName) &&
                password.equals(user.password);
    }

    @Override
    public int hashCode() {
        return Objects.hash(id, userName, password, age, gender);
    }


}

InputInfoException.java

package StringRegularExpression;

public class InputInfoException extends Exception {
    public InputInfoException() {
    }

    public InputInfoException(String message) {
        super(message);
    }

    public InputInfoException(String message, Throwable cause) {
        super(message, cause);
    }

    public InputInfoException(Throwable cause) {
        super(cause);
    }

    public InputInfoException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

小结：这算是一个结构比较完整的注册功能，User类中的get方法，set方法，hasCode方法等都以定义，主函数中也有对异常的处理。通过这个demo主要还是学会使用正则表达式处理数据，在完整项目中可以更加方便的处理数据。
