title: C/objC/C++/Java compilers
body: <p>I downloaded NetBeans (for first time) to use Java and found that it can handle C/C++ etc too.  </p>
  
  <p>Wanted to know following --</p>
  
  <p>01- Is there any better C++ tool (IDE) other than NetBeans and MS Visual Studio? Better means very mature and popular (and free).</p>
  
  <p>02- What is the difference between GNU Java and Sun Java compilers?</p>
  
  <p>02- Is there any other popular C/ObjC/C++ complier out which is free, mature and popular?</p>
  
  <p>Thank you for the reply.</p>
