Java how to format a string? -


मेरे पास निम्न स्ट्रिंग है: 

  स्ट्रिंग x = "020120765";   
 मुझे इस स्ट्रिंग को  02 0120765  के रूप में चाहिए। एक संभावना है:  
  x = x.substring (0,2) + "+ + x.substring (2, x.length ());   
 या:  
  x = स्ट्रिंग। प्रारूप ("% s% s", x.substring (0, 2), x.substring (2 ));   
 क्या कोई अन्य बेहतर या सुरुचिपूर्ण तरीका है? मैं regex की दिशा में सोच रहा हूँ मैंने निम्नलिखित की कोशिश की है:  
  x = स्ट्रिंग। प्रारूप ("% s% s", x.split ("\\ d {2}"));   
 लेकिन यह काम नहीं करता है   
 
 
 एक और विकल्प  
  x = x.replaceAll ("(। ।) (। +) "," $ 1 $ 2 ");
