FAQs on Lecture 27 Taking Input from Keyboard in Java Hindi Video Lecture - Java Programming Fundamentals: For Beginners (in Hindi) - Back-End Programming
| 1. कैसे जावा में कीबोर्ड से इनपुट लिया जाता है? |  |
उत्तर: जावा में कीबोर्ड से इनपुट लेने के लिए, हम Scanner क्लास का उपयोग करते हैं। इसके लिए, हम पहले Scanner क्लास को इंपोर्ट करते हैं और फिर Scanner ऑब्जेक्ट बनाते हैं। इसके बाद, nextInt(), nextDouble(), nextLine() आदि जैसे मेथड का उपयोग करके इनपुट ले सकते हैं।
| 2. क्या हम जावा में किसी अन्य तरीके से इनपुट ले सकते हैं? | |
उत्तर: हां, जावा में इनपुट लेने के लिए अन्य भी तरीके हैं। हम Command Line Arguments, BufferedReader, Console क्लास का उपयोग करके भी इनपुट ले सकते हैं। ये तरीके भी प्रयोग किए जाते हैं लेकिन Scanner क्लास अधिक प्रचलित है।
| 3. क्या हम जावा में कीबोर्ड से अनलिमिटेड इनपुट ले सकते हैं? | |
उत्तर: जी हां, जब तक कीबोर्ड पर इनपुट नहीं दिया जाता है या यहां तक कि एंटर नहीं दबाया जाता है, हम जावा में अनलिमिटेड इनपुट ले सकते हैं। इसे बंद करने के लिए हम उपयोगकर्ता को विशेष कोड द्वारा सूचित कर सकते हैं।
| 4. क्या हम जावा में अक्षरों को कीबोर्ड से पढ़ सकते हैं? | |
उत्तर: हां, हम जावा में कीबोर्ड से अक्षरों को पढ़ सकते हैं। इसके लिए, हम next() या nextLine() मेथड का उपयोग कर सकते हैं। next() मेथड एक शब्द पढ़ता है जबकि nextLine() मेथड एक पूरी पंक्ति पढ़ता है।
| 5. क्या हम कीबोर्ड से इनपुट लेने के लिए अनिश्चित संख्याओं का उपयोग कर सकते हैं? | |
उत्तर: हां, हम कीबोर्ड से इनपुट लेने के लिए अनिश्चित संख्याओं का उपयोग कर सकते हैं। इसके लिए, हम nextInt() या nextDouble() मेथड का उपयोग कर सकते हैं। ये मेथड एक संख्या पढ़ते हैं और इसे अपनी जरूरत के हिसाब से उपयोग कर सकते हैं।
