Java regex wildcard not accepted -

  स्ट्रिंग depend2 = "सफलता (जॉब 1) एण्ड एन (जॉब 2)"; Depend2 = depend2.replaceAll ("[\\ s]। (? I) [snd] [\\ s] * \\ (", ""); सिस्टम। आउट.प्रिंटलाइन (निर्भर 2);   
  सफलता (नौकरी 1) ANDjob2)  
 
 इसके बजाय यह आउटपुट करता है 
 
  सफलता (जॉब 1) और एन (जॉब 2)

[\\ s] (? I) [snd] यह आपके regex में यह सुनिश्चित करता है कि अंतरिक्ष के भीतर मौजूद एक अक्षर मौजूद होना चाहिए और n ( शून्य या अधिक रिक्त स्थान के साथ ( प्रतीक )। लेकिन वास्तव में एक अक्षर नहीं है। इसलिए आपका रीजेक्स विफल रहता है और कोई भी प्रतिस्थापन किए बिना मूल स्ट्रिंग देता है। 

  स्ट्रिंग निर्भर 2 = "सफलता ( नौकरी 1) और एन (जॉब 2) "; निर्भर2 = निर्भर 2.रेलेस All (" \\ s (? I) [snd] \\ s * \\ ("," "); सिस्टम.आउट.प्रिंटलाइन (निर्भर 2);   
  आउटपुट:   
  सफलता (नौकरी 1) ANDjob2)  
 
  स्पष्टीकरण:  
 
  \ श्वेत स्थान (\ N, \ r, \ t, \ f, और "") (? I) इस ब्लॉक के लिए झंडे सेट करें (केस-असंवेदनशील) (साथ ^ और $ सामान्य रूप से मेल खाता है) (साथ में 'एस', 'एन', 'डी' के सफेद अक्षर (\ n, \ r, \ t, \ f, और " ) (0 या अधिक बार) \ ('('

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
