Can you help resolve these errors - I have a java program with four classes and one main class - they need to be broken up this way per the assignment. It worked when they were all in one .java file now they do not.

//Main

import java.util.Scanner;

import Employees.java;

import Address.java;

import Name.java;

import Date.java;

public class EmployeesSystem

{

public static void main(String[] args)

{

//Set the number of employees

System.out.println("Enter the Number of Employees: ");

Scanner scnr = new Scanner(System.in);

int n = scnr.nextInt();

// enter the values

//System.out.println("Enter the Data in Employee Array ");

int Id;

String first, last;

int month, day, year;

String streetNum, street, streetType, city, state;

int zip;

// Now creating Employee array of Size n

Employee[] EmpArr;

EmpArr = new Employee[n];

for (int i = 0; i < n; i++)

{

EmpArr[i] = new Employee();

System.out.println(" Enter the details for theEmployee "+(i+1));

System.out.println("Enter the Employee ID ");

Id = scnr.nextInt();

System.out.println("Enter the Employee First Name and Last Name ");

first = scnr.next();

last = scnr.next();

while (true)

{

System.out.println("Enter the Employee Hire Date "

+ ",i.e 3 11 2018, separated by a space");

month = scnr.nextInt();

day = scnr.nextInt();

year = scnr.nextInt();

if (month < 1 || month > 12 || day < 1 || day > 31

|| year < 1900 || year > 2020)

System.out.println("Invalid date. Please input again ");

else

break;

}

System.out.println("Enter the Address "

+ ",i.e street number, stree name, stree type, city, state and zip "

+ "separated by a space");

streetNum = scnr.next();

street = scnr.next();

streetType = scnr.next();

city = scnr.next();

state = scnr.next();

zip = scnr.nextInt();

EmpArr[i].setEmpId(Id);

EmpArr[i].setEmpName(first, last);

EmpArr[i].setHireDate(month, day, year);

EmpArr[i].setEmpAddress(streetNum, street, streetType, city, state,

zip);

scnr.nextLine();

}

// Now Print the Employee Data

Name xName;

Address xAddr;

Date xHireDate;

for (int i = 0; i < n; i++)

{

Id = EmpArr[i].getEmpNumb();

xName = EmpArr[i].getEmpName();

xAddr = EmpArr[i].getEmpAddress();

xHireDate = EmpArr[i].getHireDate();

System.out.println("Id " + Id + " Name " + xName.first + " "

+ xName.last);

System.out.println("Address : " + xAddr.streetNum + " "

+ xAddr.street + " " + xAddr.streetType + ", " + xAddr.city

+ " , " + xAddr.state + "," + xAddr.zip);

System.out.println("Hire Date: " + xHireDate.month + "-"

+ xHireDate.day + "-" + xHireDate.year);

System.out.println();

System.out.println();

}

}
