How do I add nodes at index in Java? - 


  सार्वजनिक शून्य addAtIndex (इंट पेलोड, इंट इंडेक्स) AmishException फेंकता {if (index == 0) {this। addFront (पेलोड); } और अगर (सूचकांक == this.length () - 1) {this.addEnd (पेलोड); } और अगर (इंडेक्स और लेफ्टिनेंट; यह.नंबरऑफएलेमेंट्स || इंडेक्स & gt; this.length () - 1) {नया एम्श एक्सपैशन ("लिंक्डलिस्ट त्रुटि: इंडेक्स:" + इंडेक्स + "बाउंड से बाहर है !!!"); } और {}}

मेरे पास कुल में चार कक्षाएं हैं, वे बिना किसी समस्या के सामने और अंत में नोड्स जोड़ सकते हैं, लेकिन मुझे यह पता नहीं लग सकता है कि उन्हें कैसे जोड़ें एक अनुक्रमणिका। मेरे पास एक विधि है जो लंबाई निर्धारित करती है, लेकिन दो घंटे बाद मैं इसे समझ नहीं सकता। यह वह तरीका है जो सूचकांक में जोड़ देगा, लेकिन अब यह सब कुछ एक अपवाद फेंकता है और आगे और पीछे जोड़ता है।
