question: public static boolean equals ( float [ ] field1 , float [ ] field2 ) { if ( field1 == null || field1 . length == 0 ) { return field2 == null || field2 . length == 0 ; } else { return Arrays . equals ( field1 , field2 ) ; } }
target:  Checks repeated float field equality; null-value and 0-length fields are considered equal.
