public class Product {
private String name;
private double cost;
public Product(String n, double c) {
name=n;
cost=c;
}
public String getName() {
return name;
On the left is code for a class called Product.
Fill in the blanks in the code on the right in order to create three appropriate Product
instances and add them to the cart ArrayList. Use the output of the code, shown
below the code, to guide you.
}
public double getCost() {
return cost;
}
public String toString() {
return (name + "$" + cost);
}
public static void addProducts (ArrayList c) {
add(new Product("Shampoo", 13.89));
add(new Product("Bread",4.99));
add(new Product("Cereal", 7.49));
}
public static void main(String[] args) {
ArrayList cart = new ArrayList();
ddProducts (cart);
for (Product p : cart) {
System.out.println(p);
}
}
Output:
Shampoo $13.89
Bread $4.99
Cereal $7.49

It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4arrow_forward

- # Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`.
