उत्तर: BufferedWriter का उपयोग फ़ाइल में डेटा लिखने के दौरान लिखने का प्रदर्शन बेहतर बनाने के लिए किया जाता है। यह डेटा को बफ़र करके लिखता है, जिससे डिस्क अभीष्ट में डेटा लिखने की आवश्यकता को कम करता है।
| 4. FileWriter और BufferedWriter में क्या अंतर है? | |
उत्तर: FileWriter और BufferedWriter दोनों क्लासेज़ फ़ाइल में डेटा लिखने के लिए उपयोग होती हैं, लेकिन उनमें कुछ अंतर होता है। BufferedWriter, जब इसे FileWriter के साथ उपयोग किया जाता है, डेटा को बफ़र करके लिखता है, जबकि FileWriter तुरंत डेटा लिखता है। BufferedWriter का उपयोग करने से लिखने का प्रदर्शन बेहतर होता है और डिस्क अभीष्ट में डेटा लिखने की आवश्यकता को कम करता है।
| 5. क्या BufferedWriter का उपयोग केवल टेक्स्ट फ़ाइलों में ही किया जा सकता है? | |
उत्तर: नहीं, BufferedWriter का उपयोग टेक्स्ट फ़ाइलों के साथ ही बाइनरी फ़ाइलों में भी किया जा सकता है। BufferedWriter के माध्यम से हम बाइनरी डेटा को भी लिख सकते हैं, जैसे कि इमेज या वीडियो फ़ाइल में डेटा लिखने के लिए।
