Exercise 8.9:

Reading a binary file (1: BMP)


Create a Java program to check if a BMP image file seems to be correct.

It must see if the first two bytes are B and M (ASCII codes 0x42 and 0x4D).

Source Code:

public class Main
    public static void main(String[] args)
		byte data1, data2;

		//Open file
		BinaryReader myFile;
		myFile = new BinaryReader(File.Open("1.bmp", FileMode.Open));

		// Read data
		data1 = myFile.ReadByte();
		data2 = myFile.ReadByte();

		//Close file

		//Check Data
		if ((data1 == 0x42) && (data2 == 0x4D)) // B M
			System.out.println("It seems to be a BMP file");
			System.out.println("It DOES NOT seem to be a BMP file");
