question: public static boolean equals ( Object [ ] array1 , Object [ ] 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 ++ ) { Object e1 = array1 [ i ] , e2 = array2 [ i ] ; if ( ! ( e1 == null ? e2 == null : e1 . equals ( e2 ) ) ) { return false ; } } return true ; }
target:  Compares the two arrays.
