Question

Create a class named Sandwich that contains the following data fields:

• MainIngredient - of type String
• Bread - of type String
• Price - of type Double

Include get and set methods for these fields. The methods should be prefixed with 'get' or 'set' respectively, followed by the field name using camel case. For example, setMainIngredient.

Use the application named TestSandwich that instantiates one Sandwich object and demonstrates the use of the set and get methods to test your class.

TestSandwich.java (provided):

class TestSandwich
{
public static void main (String args[])
{
Sandwich sandwich = new Sandwich();
sandwich.setMainIngredient("tuna");
sandwich.setBread("wheat");
sandwich.setPrice(4.99);
System.out.println("You have ordered a " +
sandwich.getMainIngredient() + " sandwich on " +
sandwich.getBread() + " bread, and the price is " + sandwich.getPrice());
}
}
