Java Scanner - Read Registration Data from Console

In this post, we will see how to use Scanner class to read user registration data from console and we populate all input data into Register class object.

Java Scanner - Registration Example

package com.java.tutorials.projects.login;

import java.util.Scanner;

public class Registration {

    static Register register = new Register();

    public static void main(String[] args) {

        try (Scanner scanner = new Scanner(System.in)) {
            System.out.print(" Enter firstName => ");
            String firstName = scanner.nextLine();
            register.setFirstName(firstName);

            System.out.print(" Enter lastName => ");
            String lastName = scanner.nextLine();
            register.setLastName(lastName);

            System.out.print(" Enter userName => ");
            String userName = scanner.nextLine();
            register.setUserName(userName);

            System.out.print(" Enter password => ");
            String password = scanner.nextLine();
            register.setPassword(password);

            System.out.print(" Enter emailId => ");
            String emailId = scanner.nextLine();
            register.setEmailId(emailId);

            System.out.print(" Enter phoneNo => ");
            long phoneNo = scanner.nextLong();
            register.setPhoneNo(phoneNo);

            System.out.println(register.toString());
        }
    }
}

class Register {
    private String firstName;
    private String lastName;
    private String userName;
    private String password;
    private String emailId;
    private long phoneNo;
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getEmailId() {
        return emailId;
    }
    public void setEmailId(String emailId) {
        this.emailId = emailId;
    }
    public long getPhoneNo() {
        return phoneNo;
    }
    public void setPhoneNo(long phoneNo) {
        this.phoneNo = phoneNo;
    }
    @Override
    public String toString() {
        return "Register [firstName=" + firstName + ", lastName=" + lastName + ", userName=" + userName + ", password=" +
            password + ", emailId=" + emailId + ", phoneNo=" + phoneNo + "]";
    }
}

Output:

 Enter firstName => Ramesh
 Enter lastName => Fadatare
 Enter userName => Ramesh Fadatare
 Enter password => Password
 Enter emailId => ramesh@gmail.com
 Enter phoneNo => 1234567899
Register [firstName=Ramesh, lastName=Fadatare, userName=Ramesh Fadatare, password=Password, emailId=ramesh@gmail.com, phoneNo=1234567899]
