PBJ 1200: Introduction to Peanut Butter and Jelly

🥜 🧈 🍇 🍞 🥛 🍽️ 🥪

What is your name?

Hello, ! As a student who likes peanut butter & jelly, you should know how to make one! Well, you're in luck as we will teach you how to code the tastiest PB&J ever <3

Sadly, no one is perfect and this code is ridden with bugs!
Since no want wants a bug-infested PB&J, help us debug everything and you will be rewarded handsomely.

Part 1: Prepare the Bread

Files to submit: Bread.java, Knife.java

/*
This code contains the PBAndJ class, Bread class, and the main method.
*/

public class PBAndJ {
public static void assemble (Bread b1, Bread b2) {
System.out. println( "Hello World" )
}

public static void main() {
Bread topBread = new Bread("wheat");
Bread bottomBread = new Bread("wheat");
Knife knife = new Knife();
}
}

class Bread {
boolean spreaded;
boolean isCut;
boolean isToasted;
String expDate;
String flavor;

Bread(String flavor) {
expDate = ().toString();
isToasted = false;
this.flavor = flavor;
this.spreaded = false;
this.cut = false;
}

public String getExpDate() {
return expDate;
}
}
TERMINAL

Error: Bread is expired!
