What is Hello, World?
1.
The first program learned in any given programming language: very easy.
Basic:
10 print"Hello, World"
Java:
System.out.println("Hello, World");
C,C++:
std::cout<<"Hello, World";
He doesn't know shit about hacking, hell, he couldn't even "hello, World"!
2.
The first program you learn in a basic survey of a new programming language. Sometimes, but not always the program's sole function is to output the words "Hello World" on the display.
I've been working with Enterprise Java for weeks, and I'm not even at the "Hello, World" level.
