मैं लागू करने की कोशिश कर रहा हूँ एक ऑपरेटिंग सिस्टम असाइनमेंट के रूप में एक लॉग स्ट्रक्चर फाइल सिस्टम। इसमें सबसे हालिया डेटा फ़ाइल के अंत में रखा गया है। यही कारण है कि मैं रिवर्स ऑर्डर में टेक्स्ट फ़ाइल "लाइन-बाय-लाइन" को पढ़ना चाहता हूं क्या यह संभव है?

रिवर्सलाइन इनस्टस्ट्रीम देखें:

यह एसई प्रश्न को संदर्भित करता है 

  में = नया बफ़्टेड रीडर (नया इन्पुटस्ट्रीमरेडर (नया रिवर्सलाइन इंटरस्ट्रिम स्ट्रीम (फ़ाइल))); जबकि (सच) {स्ट्रिंग रेखा = in.readLine (); अगर (रेखा == शून्य) {ब्रेक; } System.out.println ("X:" + लाइन); }

(धन्यवाद, @ मार्क ओ'डोनोह)
