Show the ERD with relational notation with crowfoot. Drexel University Financial Office has made contracts with several local ba
nks to help its university members to easily obtain small loans to $10,000 for each year. For this purpose, there are two types of university members - either students or employees. A student loan has a low interest rate, and students will begin to pay back after one year of their college graduation with a lixed amount per month. An employec loan has a higher interest rate than student loans, and employees need to pay certain amounts cach month from the 2nd month of the loan approvals. Each loan belongs to only one bank. Obviously, a bank approves many loans. For each loan, there is a loanff, interest rate, approved amount, monthly payment amount, and the beginning date of loan payments. For each loan, the office also keeps tracks of history of payments to the loan, including payment date and payment amount. The office also wants to know university member ID, name, and address. In addition, each student has major, while faculty and staff have the department name they work for and their job titles. For banks, we just keep bank number and name. You may add other unstated, but common-sense oriented, facts to the ERD, but you must represent the facts stated above.

Answer:
Explanation:
The following code is written in Java. It creates the Bug class with the position and direction variables. Then it creates a constructor, move method, turn method, and getPosition method. Finally, a bug object called bugsy is created in the main method, and we move it once to the right, then again to the right, and then we turn it and move it 5 times to the left, printing out the position when it is done moving. Output can be seen in the attached picture below.
class Brainly {
public static void main(String[] args) {
Bug bugsy = new Bug(10);
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
bugsy.turn();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
bugsy.move();
System.out.println("Current bug position: " + bugsy.getPosition());
}
}
class Bug {
char direction = 'r';
int position = 0;
public Bug(int initialPosition) {
this.position = initialPosition;
}
public void turn() {
if (this.direction == 'r') {
this.direction = 'l';
} else {
this.direction = 'r';
}
}
public void move() {
if (this.direction == 'r') {
this.position += 1;
} else {
this.position -= 1;
}
}
public int getPosition() {
return this.position;
}
}
