Prototype for the Parameterized Constructor, public Customer(String name, String email)
Use 'equals()' and 'equalsIgnoreCase()' to compare the email ids[Refer sample input & output ].
Consider the main class "Main.java".

Date
Rex figured out that the binary forms of the date, month, and year were 2 bits, 2 bits, and 2 bits rotated left in his LED board. Write a program to change the incorrect date, month, and year. use the Integer Wrapper Class rotateRight() method to print the correct date in International format.
The date format to be displayed in the output is (yyyy-mm-dd).
Input Format:
The first line is an integer that corresponds to the incorrect day number.
The second line is an integer that corresponds to the incorrect month number.
The third line is an integer that corresponds to the incorrect year.
Output Format:
The Output should display the correct date in a single line separated by slashes in the international format.
Sample Input:
20
36
7944
Sample Output:
1986/9/5
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int a = sc.nextInt();
int b = sc.nextInt();
int c = sc.nextInt();
a = Integer.rotateRight(a, 2);
b = Integer.rotateRight(b, 2);
c = Integer.rotateRight(c, 2);
System.out.println(c+"/"+b+"/"+a);
}
}
