• In this program, an array named ‘bytes’ is created which contains some elements in it. This array is of byte type.
• The string method format() is used for converting every element in the byte array to its corresponding hexadecimal value through continuous iterations.
• The .format() method formats the input byte to %02X which means 02 places of hex (X) digits are displayed. This converted value is stored in the variable st.
