How cant i show jframe or jdialog with string class name in java swing -


मैं JFrame या JDialog के साथ string कैसे दिखा सकता हूँ जावा वाव में वर्ग का नाम

उदाहरण: मेरे पास JFrame नाम com.tan.ui.NewJFrame में स्ट्रिंग < / कोड> और मुझे यह फ्रेम दिखाना है

पहले, आपको एक वर्ग प्राप्त करना होगा संदर्भ ...

<पूर्व> कक्षा फ़्रेम वर्ग = वर्ग। ForName ("com.tan.ui.NewJFrame");

अगला, आप वर्ग के एक नए उदाहरण बनाते हैं ... 

  JFrame frame = (JFrame) frameClass.newInstance ();
