please help completing this short assigment that needs to be done in linux,
in java code create a program
DO NOT USE JAVA'S AUTOMATIC CONVERSION METHODS
to do the following:
In your Ubuntu, linux, using terminal mode ONLY, do the following:
- Create a folder named pgm2
some of the lines in the file have spaces at the bigining, read the lines overcoming that trick intructed by the professor
MAKE SURE NOT TO CHANGE THE FILE NAME
Each record in this file represents the location of an error found in RAM
Assume your computer has 4 gigs of RAM, each gig in a different memory chip, therefore you have 4 one gig RAM chips. A gigabyte contains 1,073,741,824 or 1024^3 or 2^30 bytes, which is also equivalent to 1,048,576 kilobytes or 1,024 megabytes.
These are the addresses in each RAM chip in a computer with 4 (gigs) of RAM:
decimal adresses
RAM chip 0 contain addresses: 0 - 1,073,741,823 bytes
RAM chip 1 contain addresses: 1,073,741,824 - 2,147,483,647 bytes
RAM chip 2 contain addresses: 2,147,483,648 - 3,221,225,471 bytes
RAM chip 3 contain addresses: 3,221,225,472 - 4,294,967,295 bytes
- In the same folder (pgm2), use an editor in terminal mode, create a Java program to do the following:
- Open the text file
- Read each record in the file
- Convert the record to binary
- Convert the binary result to decimal
- Find in which RAM chip is the decimal error found
- Print the RAM memory chip where the error is located for each record as follows: example:
hex number = binary number = decimal number located at x RAM chip
CREATE YOUR OWN METHODS THAT WILL CONVERT HEX TO BINARY AND BINARY TO DECIMAL
DO NOT USE JAVA'S AUTOMATIC CONVERSION METHODS, IT HAS TO BE DONE DOING MATH ONLY
