Pity the Fool
September 22nd, 2007 by RadarI feel sorry for the people who code in Java and you should too. Their “hello world” program is 5 lines long, 5 times longer than Ruby’s. Not only do you have to write out five lines, but then you have to compile and then execute it.
(all Java examples stolen from the [url=http://en.wikipedia.org/wiki/Java_%28programming_language%29]Java (programming language) page[/url]
[code="Java: Hello World"]
public class Hello {
public static void main(String[] args) {
System.out.println(”Hello, World!”);
}
}
[/code]
Ruby’s Hello World on one line:
[code="Ruby: Hello World (irb)"]
puts “hello world”
[/code]
And then how about this example in order to tell if a number is odd or even:
[code="Java: Odd Or Even"]
public class OddEven {
private int input;
public OddEven() {
input = Integer.parseInt(JOptionPane.showInputDialog(”Please Enter A Number”));
}
public void calculate() {
if (input % 2 == 0)
System.out.println(”Even”);
else
System.out.println(”Odd”);
}
public static void main(String[] args) {
OddEven number = new OddEven();
number.calculate();
}
}
[/code]
And Rails’:
[code="Rails: Odd or Even (script/console)"]
>> 2.even?
=> true
[/code]
