question: public static Cache . Entry makeRandomCacheEntry ( byte [ ] data , boolean isExpired , boolean needsRefresh ) { Random random = new Random ( ) ; Cache . Entry entry = new Cache . Entry ( ) ; if ( data != null ) { entry . data = data ; } else { entry . data = new byte [ random . nextInt ( 1024 ) ] ; } entry . etag = String . valueOf ( random . nextLong ( ) ) ; entry . serverDate = random . nextLong ( ) ; entry . ttl = isExpired ? 0 : Long . MAX_VALUE ; entry . softTtl = needsRefresh ? 0 : Long . MAX_VALUE ; return entry ; }
target:  Makes a random cache entry.
