Html – not really a programming language :p

JavaLanguage:

public class Hello {
public static void main(String []args) {
System.out.println("Hello World");
}
}


Object oriented Java

class Greeting {
void greet(Named target) {
System.out.println("Hello, " + target.getName() + "!");
}
}

interface Named {
String getName();
}

class World implements Named {
String getName() {
return "World";
}
}

Greeting greeting = new Greeting();
greeting.greet(new World());
}
}


Swing Java

}


JavaApplet:

PL/SQL

Python

You copy the following text into a file and call the file (hello.py) (remember python is sensitive of it’s indenting, which rocks )

print "hello world"
Now invoke the interpreter and pass it your file with the single command: python hello.py
