I am getting the following error: SalaryCalc.java:41: error: variable shift might not have been initialized if(shift==0) ^ 1 error

Please FIX

This is my Java code:

import java.util.Scanner;
public class SalaryCalc
{
double Rpay=0, Opay=0;
void calPay(double hours, double rate){
if(hours<=40){
Rpay = hours * rate;
Opay = 0;
}
else {
double Rhr,Ohr;
Rhr = 40;
Ohr = hours-Rhr;
Rpay = Rhr * rate;
Opay = Ohr * (1.5*rate);
}
}
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String name;
int shift;
Double rate, hours;
System.out.println("Pay Calculator");
System.out.println("Enter Your Name");
name=sc.next();
System.out.println("Enter Your Shift, Enter 0 for Day, Enter1 for Night");
System.out.println("0=Day, 1= Night");
System.out.println("Enter Number of Hours Worked");
hours=sc.nextDouble();
System.out.println("Enter Hourly Pay");
rate=sc.nextDouble();
SalaryCalc c= new SalaryCalc();
c.calPay(hours,rate);
Double Tpay= c.Rpay+ c.Opay;
System.out.println();
System.out.println("Calculate Pay");
System.out.println("Employee Name: "+name);
System.out.println("Employee Regular Pay: "+c.Rpay);
System.out.println("Employee Overtime Pay: "+c.Opay);
System.out.println("Employee Total Pay: "+Tpay);
if(shift==0)
{
System.out.println("Employee PayPeriod is Friday");
}
else{
System.out.println("Employee PayPeriod is Saturday");
}
}

Use a 1 dimensional array object to create a 2 dimensional table object. Then modify to create a triangular table.

Objective -> create an array of dynamic objects of RowAray inside Table i.e. an Aggregate. See Specs RowAray.h, Table.h Then create a triangular table, i.e. Triangle.

Fill each cell with random 2 digit integers. The example Table has 8 columns of RowAray objects each filled with 6 rows of random 2 digit numbers.

Then create a triangular table using the concept of the original table.

Complete the class implementations RowAray.cpp, Table,cpp, and Triangle.cpp use the driver program, obtain similar results.

When complete for #rows=#cols, then create a version 2 that does a random number of cols per row with sorted column size output like the first assignment for the Triangular Matrix.

We will augment this assignment later and progress to templates.

For this assignment, pretend you have been hired by a school district to create an application enabling access to educational videos freely available on the Internet.

For examples of places where these videos are available, check out this page:

https://www.refseek.com/directory/educational_videos.html (Links to an external site.).

For this assignment, you are responsible for developing a database schema (both conceptual and physical) to support this application. The schema must support the following application features:

1. It should be possible to efficiently search the application for videos, filtering on the following characteristics:
   • Title (required)
   • Keywords (note that a video may have multiple keywords)
   • Length of Video (required)
   • Appropriate Grade Level (optional)
   • Video Source (i.e. which of the sites referenced on the page above houses the video. required.)
2. It should be possible for teachers to comment on videos. Each comment should have the following fields:
   • Timestamp (required)
   • Name of teacher (optional)
   • Rating (1 to 5 stars, optional)
   • Text of comment (required)

The submission for this assignment should include the following artifacts:

• An entity-relationship diagram for the conceptual schema. You can do this on paper or whiteboard and submit a photograph, or do it using diagramming software and submit a screen shot or PDF. (Please do not submit a file in the diagramming software's native format.)
• A physical schema in the form of SQL CREATE TABLE statements. Please submit the SQL and not the database file (or files) itself.
• SQL INSERT statements creating at least 3 sample video records, each of which should have at least 2 keywords. Note that you will need to insert into multiple tables for each record if the assignment was done correctly.

This assignment can be completed adequately using as few as four tables. Your schema may end up with more tables and that is fine, but if you end up with more than 7-8 tables there is a good chance you are overthinking things.

Brief Introduction

Suppose that you are an analyst for the ABC Company, a large consulting firm with offices around the world. The company wants to build a new knowledge management system that can identify and track the expertise of individual consultants anywhere in the world on the basis of their education and the various consulting projects on which they have worked. Assume that this is a new idea that has never before been attempted in ABC or elsewhere. ABC has an international network, but the offices in each country may use somewhat different hardware and software. ABC management wants the system up and running within a year.

Mark Arnez of Aspen consulting has been contacted by a client who represents an international company with locations in your city, in Toronto, and in London. Each location has a plant for making parts for boilers used in large buildings. There also are sales and parts distribution offices at the plants. All buildings currently are networked using 10-Mbps communications to each workstation or server and 100-Mbps communications between floors. The client is exploring ways to link the business networks at all three locations. Form a team to determine the best way to connect the locations. Use the internet to research some gross estimates of the costs.

3-1. On your first visit with gray sharma, he tells you he would like to know about some basic network designs. use microsoft paint or another drawing package to draw examples of the basic network topologies for gray. then, use the space below to summarize those topologies.

Explain the advantages and disadvantages of the topologies you summarized for gray in Assignment 3-1. Based on what you know at this point, which topology would you recommend for the physicians building? why would you recommend it?
