I am trying to print the hexadecimal and then the ASC11, but it is not displaying correct. Can you please review my code nad provided feedback. 
 
Current format : 

File contents: C:\Users\shari\OneDrive\Documents\testfile.dat

 

Hexadecimal:0000000001

ASC11:2

ASC11:3

ASC11:4

ASC11:5

ASC11:6

ASC11:7

ASC11:8

ASC11:9

ASC11:10

Requirment dispaly example :

You should display the 10 bytes in hex first, then the ASCII charatter.  For readability, put spacing between the hex and the ASCII.  A example of printing the first 4 lines of a file is shown below:

7c 31 7c 0d 0a 44 75 6d 62 6c     .1...Dumbl

Write a program that will use a FileInputStream to read bytes from a file, and display both a hex version of the byte, and it's corresponding ASCII code

    int returnVal = fc.showOpenDialog(null);
 
    if (returnVal == JFileChooser.APPROVE_OPTION) {
        File file = fc.getSelectedFile();
        System.out.println("File contents: " + file.getAbsolutePath());
        System.out.println();
        showContents(file);

Follow-up Question

I am getting an error at my while statement. It says Type mismatch and wants me to change the vaule type to bollean vs int. But if I do that the greater than function does't work. Do you see any errors in my code ?

 

public class Files{

 

public static void main(String arpgs[]) {

JFileChooser fc = new JFileChooser();

intreturnVal = fc.showOpenDialog(null);

 

if (returnVal == JFileChooser.APPROVE_OPTION) {

File file = fc.getSelectedFile();

System.out.println("File contents: " + file.getAbsolutePath());

System.out.println();

showContents(file);

}

}//Input File is read in binary and output files print in Hex and ASC11

private static void showContents(File file){

//Create an input file stream using try/catch block. This will automate the closing of the file.

//FileInputStream Reads files

try ( FileInputStream incomingFile = new FileInputStream (file))

{//create a variable to read the file )

intvalue =0;

intcount = 0;

 

while (value= incomingFile.read())!= -1){

 

//Print as Hex and ASC11

System.out.printf("%02X ", value); //

 

System.out.print((char) (value >= 32 && value <= 126 ? value : '.'));

count++;

 

if(count % 10 ==0)

{

System.out.println();

}

}

// Print ASCII character if printable, else '.'

 

 

//Print Hex and ASC11 using printf %02X = HEX with leading zeros

 

// increase the count

 

//Try/Catch Block closes the file.

} catch (IOException e) {

//print error message

e.getMessage();

}

 

 

}

}
