Question about the task Sequential file output
Java Core, Level 6, Lesson 13
Under discussion
Last Condition: "The output must contain the contents of the first file."There's several layers to this question: 1) This sounds ignorant to ask at this point, but how in the heck does one use the console interface in IntelliJ?

My code is now identical to the solution but still generates notserializableexception The only differences I can find: 1. The names of the arguments in the readObject and writeObject methods in the B class. Instead of "in" and "out" I use "aInputStream" and "aOutputStream". Shouldn't matter, right? 2. The order in which classes are declared. I have A and B declared before Main, the s
