You escaped the first vault — but that was the lobby. Vault II has four levels, and each one is harder than the last. A level stays sealed until you beat the one above it. Everything you need, you've already learned: printing, variables, data types, and operators.
Vault I locks had one error each. This lock has two errors in the same line. Fix both at once:
System.out.println(Vault two awaits)
Two variables guard this door, and each one has the wrong relationship with quotation marks. Fix both declarations:
int floors = "12"; String exitSide = West;
Nothing is broken here — the code runs perfectly. The lock opens only if you can predict the output without running it. Type EXACTLY what each program prints.
int code = 8;
code = code + 4;
int boost = 2;
code = code * boost;
System.out.println("Code: " + code);
System.out.println(1 + 2 + " keys");
No broken code. No code at all. Write it yourself — two lines:
1) Declare an int named escape holding the value 4055.
2) Print exactly Door code: 4055 — but the door scanner rejects hardcoded digits: the number must come from your variable, not from inside the quotes.
