इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 23 उत्तर

मैं निश्चित नहीं हूँ यह जावा में संभव है इसके अलावा, मैं यह जानने में सक्षम नहीं हूं कि इसके लिए Google पर क्या सवाल है। वैसे भी, मुझे एक ऐसा तरीका चाहिए जो एक तर्क (इंटरफ़ेस या वर्ग) के रूप में ले जाता है और विधि का रिटर्न टाइप उस क्लास का एक उदाहरण है। मैं तथ्य के बाद किसी ऑब्जेक्ट को पुनः स्थापित नहीं करना चाहता।

मुझे यह निश्चित नहीं है कि यह सुविधा मौजूद है या सिंटैक्स क्या होगा। मान लें कि मेरे पास XYZ नाम का वर्ग है और यह मेरा छद्म विधि है। 

  निजी XYZ createInstance (XYZ.class, अन्य आर्ग्स) {... // XYZ का उदाहरण अन्य आर्ग्स के साथ बनाएँ नाम "_xyz_" ... वापस _xyz_; }

अब मान लीजिए कि XYZ एक सामान्य सिंटैक्स है क्या जावा में यह संभव है? किसी भी मदद के लिए धन्यवाद। 

  निजी & lt; T & gt; टी बनाने की व्यवस्था (कक्षा & lt ;? T & gt; c) {return c.newInstance (); }
