What I Think about Java

I used to love Java. But then I really thought about its limits...I never really liked it when I compare it to C. C was very simple (yet low level. We should write C# or even Python software if we are not writing a driver or something) and it was extremely powerful (It's amazing you can put Assembly registers in C), but it being (too) low-level did not help. But we didn't need to write an entire class (and then, if you are like me, you will eventually run short of class names.) for a simple pointer (for more readability) in Python. Now, yes, we do need to write classes in C#. But at least, its high-level syntax gives me an idea. If I am going to catch an exception, I will simply name the sub-class (or super, depending on how you code), "Exception class" instead of naming "Try-catch-try" as I did to annoy my co-workers. But then again, I only need a single function in C (single word) to write a Hello, World application.

Printf("Hello, World!\n") #Very similar to Python. Except that you do not need a newline character.

In Python, this is even more simplified. The f is removed and you do not need a newline character (Not sure. Haven't coded in Python for months)

But in 2.x, you need raw_input instead of print("Hello, World!")

 

But let's take a look to C++.

#include 'std_lib_facilities.h'

int main()
{
	cout << 'Hello World!\n';
	return 0;
}

Obviously, C++ is a LITTLE more verbose. And a little too complex. But in Java, there are more restrictions than creativity and limits....

System.out.println("Hello....World!"); #The newline version.
System.out.print("Hello...");
System.outprint("World!"); #The non-newline version...and the ellipse shows JVM speed.

C++ is more powerful. More creative and more hard  (to master), but it pays off well. Things in C# are simplified a bit, but MS is basically saying "Screw you" to any non-MS OS. The MS Framework (the JVM of C#) does not include support for Linux or Mac. Third party devs are working on it, but that's it, no official support.
