someone who said :

{
setOfCells = new Cell[n][n];
dimension = n;
generations = s;
}
That is a "constructor", not an "accessor".
"accessors" is not a Java term. Accessor methods are called "getters"
and "setters". It sounds a bit babyish at first, but the terms are
short and easy to remember.
The usual convention goes like this:
/**
* constructor
* @param size number of rows and columns in the matrix
* @param generations number of generations to simulate
*/
public Tableau(int size, int generations)
{
this.cells = new Cell[size][size];
this.size= size;
this.generations = generations;
}
Note that Javadoc is considered almost as important at the executable
code. Its formal structure is one of the best and most important
features of Java. Comments are not noise the way they are in most
other languages. They are the secret of bug free and easy to modify
code. They force you to think clearly about your intentions.
