private static byte[]theTestText ={0x00,0x11,0x22,0x33,0x44,0x55,0x66,0x77,(byte) 0x88,(byte) 0x99,(byte) 0xAA,(byte) 0xBB,(byte) 0xCC,(byte) 0xDD,(byte) 0xEE,(byte) 0xFF};

String str= new String(theTestText); // converted the byte array to string
char ch = str.charAt(8); // extracting a specific character from string

I want to obtain the hex value from the character 'ch' as defined in the original byte array i.e. 0x88. Is there any way to get that?

  • Yes there is. Convert the byte to a hex string. Have a look in one of those answers (as it's asked quite often) https://stackoverflow.com/search?q=[java]+byte+to+hex – SubOptimal Mar 23 '15 at 10:52

    Is that arbitrary binary data? If it's *actually* text, what text encoding was it encoded with? – Jon Skeet Mar 23 '15 at 10:52

To get the hexa value in a string: 

String str= new String(theTestText); // converted the byte array to string
char ch = str.charAt(8); // extracting a specific character from string
String hex = String.format("%04x", (int) ch); // Converting the char to a string with its hexadecimal value
