Principia Programatica - Greg Miller’s Blog

I thought this would be a fun little exercise to try. This puzzle is generally used to teach recursion in CS classes, but I have never actually tried to implement it.

An experiment was conducted in order to study the differences between programmers, engineers, and mathematicians. One programmer, one engineer, and one mathematician were all locked in separate classrooms for one week. Each classroom contained all of the normal things you’d find in a classroom: chalkboard, chalk, desks, etc. In addition to that […]

Final in Java is used to declare a class that can’t be subclassed, a method that can’t be overridden, or …
A final variable means the value won’t change, but the value can still be determined at run time:

final int i;
if ( j > 0 ){
i =1;
} else {
i = […]

I’ve seen many, many posts in forums asking about some good books to read to either get started in computer science, or what next steps to take after having read one intro book on a specific language. Of course none of them state what their goals are, other than they “want to learn to […]

To many, it should be obvious what the following code prints:

public static void main(String[] args){
int x=0;
SomeMethod(x);
System.out.println(x);
}

protected static void SomeMethod(int x){
x=1;
}

The code prints 0, because “int” is a native type and is passed by value. […]

Of course the answer is no, otherwise it wouldn’t be a very interesting post. The concept of interning is an attempt to save memory by allocating static values which match exactly to the same memory location, without regard to where they’re used in the application. But here’s in instance where it doesn’t quite […]
