public static boolean equals ( byte [ ] array1 , byte [ ] array2 ) { if ( array1 == array2 ) { return true ; } if ( array1 == null || array2 == null || array1 . length != array2 . length ) { return false ; } for ( int i = 0 ; i < array1 . length ; i ++ ) { if ( array1 [ i ] != array2 [ i ] ) { return false ; } } return true ; }
compares the two arrays .
