Explanation of Solution

a.

Program code:

Sandwich.java

//create a class Sandwitch

public class Sandwich

{

//create string variables

private String ingredient, breadType;

//create double variable

private double price;

//define a constructor

public Sandwich()

{

}

//define a method getIngredient()

public String getIngredient()

{

//return the ingredient

return ingredient;

}

//define a method setIngredient()

public void setIngredient(String ingredient)

{

//set value of the variable ingredient

this.ingredient = ingredient;

}

//define a method getBreadType()

public String getBreadType()

{

//return the breadType

return breadType;

}

//define a method setBreadType()

public void setBreadType(String breadType)

{

//set value of the variable breadType

this.breadType = breadType;

}

//define a method getPrice()

public double getPrice()

{

//return the price

return price;

}

//define a method setPrice()

public void setPrice(double price)

{

//set value of the variable price

this.price = price;

}

}

Explanation:

The above snippet of code is used create a class “Sandwich”. The class contain different static methods for store the details of sandwich. In the code,

    • Return the value of the variable “ingredient”.
  • Define the “setIngredient()” method.
    • Set the value of the variable “ingredient”.
  • Define the “getBreadType()” method.
    • Return the value of the variable “breadType”.
  • Define the “setBreadType ()” method...
