Question
Your Community Supported Agriculture (CSA) farm delivers a box of fresh fruits and vegetables to your house once a week. For this Programming Project, define the class BoxOfProduce that contains exactly three bundles of fruits or vegetables. You can represent the fruits or vegetables as three instance variables of type String .Add an appropriate constructor, accessor, and mutator methods. Also write a toString() method that returns as a String the complete contents of the box.
Next, write a main method that creates a BoxOfProduce with three items randomly selected from this list:
Broccoli
Tomato
Kiwi
Kale
Tomatillo
This list should be stored in a text file that is read in by your program. For now you can assume that the list contains exactly five types of fruits or vegetables.
Do not worry if your program randomly selects duplicate produce for the three items. Next, the main method should display the contents of the box and allow the user to substitute any one of the five possible fruits or vegetables for any of the fruits or vegetables selected for the box. After the user is done with substitutions, output the final contents of the box to be delivered. If you create additional methods to select the random items and to select valid substitutions, then your main method will be simpler to write.
Answer
public class BoxOfProduce
{
private String f1;
private String f2;
private String f3;
public BoxOfProduce(String f1, String f2, String f3) {
setFruit1(f1);
setFruit2(f2);
setFruit3(f3);
}
public void setFruit1(String f1)
{
this.f1 = f1;
}
public void setFruit2(String f2)
{
this.f2 = f2;
}
public void setFruit3(String f3)
{
this.f3 = f3;
}
public String getFruit1()
{
return f1;
}
public String getFruit2()
{
return f2;
}
public String getFruit3() {
return f3;
}
public String toString()
{
return "1 : " + f1 + "\n" + "2 : " + f2 + "\n" + "3 : " + f3;
}
}
