COMPARE PHONE NUMBER - JAVA
New App helps you discover great places to eat around or de-stress in all major cities across 20000+ merchants. Explore restaurants, spa & salons, and activities to find your next fantastic deal. Write a program to find the duplication of user accounts.
Write a Java program to get two users’ details and display whether their phone numbers are the same or not with the following class and methods.
[Note: Strictly adhere to the object-oriented specifications given as a part of the problem statement.
Follow the naming conventions as mentioned. Create separate classes in separate files.]
Consider the class User with the following private attributes/variables.
| Date Type | Variable |
| String | name |
| String | username |
| String | password |
| Long | phoneNumber |
Include appropriate getters and setters.
Prototype for the Parameterized Constructor,
public User(String name, String username, String password, Long phoneNumber)
Define the following method in the User class.
Method Name :
public boolean comparePhoneNumber(User user)
Description:
In this method compare the phone number of the two users and
return true if both the numbers are equal else return false
Consider the Main class and write the main method to test the above class.
In the main method
- Obtain the details of the user.
- Create an object for the User class using the parameterized constructor(name, username, password, phoneNumber).
- Call the method comparePhoneNumber() in the Main class.
Input and Output Format
Refer sample input and output for formatting specifications.
If both phone numbers are the same then print “Same Users” else print “Different Users”.
The output should be printed in the Main class.
Sample Input/Output 1:
[All text in bold corresponds to the input and the rest corresponds to output.]
Enter Name
john
Enter UserName
john@123
Enter Password
john@123
Enter PhoneNumber
9092314562
Enter Name
john
Enter UserName
john@12
Enter Password
john@12
Enter PhoneNumber
9092314562
Same Users
Sample Input/Output 2:
Enter Name
william
Enter UserName
william####
Enter Password
william
Enter PhoneNumber
9092314562
Enter Name
john
Enter UserName
john@123
Enter Password
john@123
Enter PhoneNumber
9092312102
Different Users
Create two classes 1) Usser
2) Main
PROGRAMS :
public class User {
private String name;
private String username;
private String password;
private long phoneNumber;
public User(String name,String username,String password,long phoneNumber){
this.name = name;
this.username = username;
this.password = password;
this.phoneNumber = phoneNumber;
}
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
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 long getPhoneNumber(){
return phoneNumber;
}
public void setPhoneNumber(long phoneNumber){
this.phoneNumber = phoneNumber;
}
boolean flag = false;
public boolean comparePhoneNumber(User user) {
if(user.phoneNumber==phoneNumber)
flag = true;
return flag;
}
import java.io.*;
import java.util.Scanner;
class Main{
public static void main(String[] args) throws Exception{
Scanner sc = new Scanner(System.in);
String name,username,password;
long phoneNumber;
System.out.println("Enter Name");
name = sc.nextLine();
System.out.println("Enter UserName");
username = sc.nextLine();
System.out.println("Enter Password");
password = sc.nextLine();
System.out.println("Enter PhoneNumber");
phoneNumber = sc.nextLong();
sc.nextLine();
User user1 = new User(name,username,password,phoneNumber);
System.out.println("Enter Name");
name = sc.nextLine();
System.out.println("Enter UserName");
username = sc.nextLine();
System.out.println("Enter Password");
password = sc.nextLine();
System.out.println("Enter PhoneNumber");
phoneNumber = sc.nextLong();
User user2 = new User(name,username,password,phoneNumber);
if(user1.comparePhoneNumber(user2))
System.out.println("Same Users");
else
System.out.println("Different Users");
}
}
