how do i code this.. i am stuck on how to read the file and put the individual int and chars into the 2d array as elemnts. since both two different variables. I would post what i have so far but i do not have anything been staring at net beans for quite some time.. also been googling/youtubing for a while

when you say "int and char" , do you mean like how the following line has numbers and characters in it?





?

Just interpret everything as a character and fill a 64x64 array of characters. Nothing in the assignment seems to indicate you would have to specifically interpret the numbers as an integer type.


This seems (at quick glance) like you just use a buffered reader to take the file into an array of 64x64, then depending on what the command string is, for each command perform some kind of matrix modification

Forgive me if I am not 100% correct on the java side I/O. I have not touched it since I finished college several months ago

ok so the numbers in the file when being initialized doesn't need a separate int declaration? becuase i need to input a .txt file in there which consists of both int and char types. and to answer your question yes. this is where im a bit confused upon.

right. Your 64x64 array should be an array of characters

do i have to convert the int to char first?

you shouldn't have to. Java's built in IO functions should take care of the reading for you.

sigh.. can u somehow give me an example of how might it look ... ? sorry im at a block right now. on how to do this part..

so far...

Create a File object to represent your file, new up a Scanner object and hook it up to read from your file. Fill in your array of characters.

Once you have that done, maybe iterate over the array to make sure it looks correct. Then figure out how to transform it based on the commands.

ok see thats the thing how do i amke it so i dont have to represent a certain file? meaning.. my instructor can put in a file of his own and it'll do the same?.. how do i define the variables for nRows /nCols?

Can you copy and paste the file here? I don't know if that will alter the structure of the file. Or try uploading the file so I can download it.
