    Java NullPointerException error in Java (Eclipse)

    Well yeah, I'm trying to my best to follow my own "convention" because I just started coding ( engineering in college). However your use of bracket does help more the understanding of the code. As for the 0000001, I was just thinking of a long number, I changed it to 11111111. Thanks both of...

    Java NullPointerException error in Java (Eclipse)

    Would you mind telling me telling me what is the NullPointer stack trace? Also I figured it out using system.out.print. Realized the array I was trying to copy was null, so I was initializing a null by a null, because modulus of 3 gives a remainder of 0,1, or 2. Silly me. However, I would...

    Help with decoders and RAM [Digital Logic]

    I'm trying to understand the concepts of it, it was not covered in my class but it is clearly stated that i have to use it. I have the circuit diagram and I needed to connect my decoder to my ram in order to make my lab work, that is to connect my decoder to a timing generator. However in this...

    Help with decoders and RAM [Digital Logic]

    So I know my lab describes the chip as 4 bits size cell. Which is fine, it clearly states that. I mean I understand that a nibble is a 4 bit number. However, sorry if I got that wrong, my class never covered the units ( really basics I know...). We only used bits or bytes. Hence my reference to...

    Help with decoders and RAM [Digital Logic]

    first i apologize for the formatting I am on a cellphone. I am in software engineering and we have to take a hardware class and we didnt need any pre requisites for that class. as for the decoder, I am aware of it being being kilobits. My question was directed towards the truth table. As in why...

    Help with decoders and RAM [Digital Logic]

    First I really don't know where I should post this (I'm assuming this place is fine, maybe coursework?) So I built a circuit that includes a 1k x 4 RAM ( so I'm assuming that stands for 4000 Kb but I wouldn't see why you'd need to write 1k x 4 RAM) Furthermore, I'm having trouble...

    Java Help with a pattern using nested loops (java)

    Hey so I have to make a pattern in the shape of a diamond as follow: 1 123 12345 123 1 So first, I wrote the code without using a variable n as the number of rows ( from an input from the user) but just the constant i = 5 ( I am sorry for the variable names, I made many patterns and...

    Discrete Math Proof: Proving Equivalence of 4 Statements

    not at all, my assumption of n being even was just wrong, but that's all I've been taught before so I thought it was a set definition. anyway case closed.
