Question

In java

Assignment Modify the code Binary File IO Example Code. The code reads and prints information about a BMP file. Modify the code so that it also prints the resolution of the BMP file (both width and height) and the number of bits per pixel. Do not use any Java library or third-party library code that reads BMP files. You must read the file using simple Java code and extract the information, similar to the code in the example. The format of a BMP file can be found at https://en.wikipedia.org/wiki/BMP file format Run your program. Your program must run successfully to receive full credıt for this homework. Take a screenshot of your program in Eclipse. The screenshot should part of the source code of your program and the output from running your program. Turn in the source code for your program also.
