Why is Java so popular

The introductory programming course at uni teaches Java, but you don't have to take it if you know a programming language. Should I teach myself python over the summer (I already know the basics) and avoid having to learn Java? Or are the haters just people who are scared of object orientation.

>Interface methods must be public. Shit.
No need for private interface methods, perhaps you should learn what polymorphism is and when you should use it.


Let me demonstrate why an interface shouldn't be forcibly public.



#include <iostream>
#include <string>

class base
{
public:
 void go()
 {
  this->set();
  std::cout << str << std::endl;
  std::cin.get();
 }
protected:
 virtual void set() = 0;
 std::string str;
};

class derived : public base
{
protected:
 void set()
 {
  str = "CUDDER";
 }
};

int main(int argc, char* argv[])
{
 base* a = new derived;
 a->go();
 delete a;
}
