question: function : bytes2hexstr byte arr , int len generate a hex string showing the value of the bytes in arr . used by me for testing this class . concode_field_sep char[] hex concode_field_sep void print concode_elem_sep void println concode_elem_sep int ubyte concode_elem_sep void int2byte concode_elem_sep void pr concode_elem_sep void pr concode_elem_sep void memcpy concode_elem_sep int uadd32 concode_elem_sep int uadd32 concode_elem_sep int uadd32 concode_elem_sep int rl concode_elem_sep void byte2int concode_elem_sep void memset
target: String function ( byte [ ] arg0 , int arg1 ) { StringBuffer loc0 = new StringBuffer ( arg1 * 2 ) ; for ( int loc1 = 0 ; loc1 < arg1 ; loc1 ++ ) { int loc2 = ( arg0 [ loc1 ] >>> 4 ) & 0xf ; loc0 . append ( hex [ loc2 ] ) ; int loc3 = ( arg0 [ loc1 ] ) & 0xf ; loc0 . append ( hex [ loc3 ] ) ; } return loc0 . toString ( ) ; }
