Subway Sandwich

Report a typo

It seems to be true that developers get inspiration from the real world, so let's consider a real-world example of the Builder Pattern: Subway sandwiches. A waiter in Subway is your Builder. You can build sandwiches step-by-step adding portions of an ingredient. We offer you to make a simple order: your task is to write some TestDrive code and get a correct output.

Sample Input 1: 

Italian
1
2
0
4

Sample Output 1: 

Bun : Italian
Salad : 1
Cheese : 2
Cucumber : 0
Ham : 4
Write a program in Java 17
import java.util.Scanner;

class Sandwich {

private String bun;
private int salad;
private int cheese;
private int cucumber;
private int ham;

public Sandwich(String bun, int salad, int cheese, int cucumber, int ham) {
this.bun = bun;
this.salad = salad;
this.cheese = cheese;
this.cucumber = cucumber;
this.ham = ham;
}

public static class Builder {

private String bun;
private int salad;
private int cheese;
private int cucumber;
private int ham;

public Builder addBun(String bun) {
this.bun = bun;
return this;
}

public Builder addSalad(int salad) {
this.salad = salad;
return this;
}
