Heroes Learn Java's Hello World

Why did the people who were just beginning to learn programming start with Hello World? Many people do not understand this problem, even some people deliberately do not start from Hello World. I have a classmate is deliberately not from Hello World start, he is from Hello xxx (xxx is his name) began, the result is, practicing n years, his code level is so rotten, often out of the bug, affecting the line running.

Programmers are an industry, and like other industries, we also have Huang (Turing?). von Neumann But we do not worship Huang, but instead in another way, that is to write Hello world. The programmer's path didn't go smoothly without the people who wrote Hello World. Why? Because he lacks a awe-inspiring heart and does not respect this industry.

There is another reason: first impressions. If we meet people, the first impression is also important for learning a language. Often, from the Hello World program you can see what a great language experience is. For example, Java to write a class to write methods, so cumbersome, very redundant, a lot of scripting language only need a line of code (such as print "Hello World"), such language is often crisp concise.

So, just learn to program the classmate, must start from Hello World
