2d array of type Space
I'm trying to make a 9x9 grid of Spaces with 1-10 int values. I'm using the java n-ide app, and am getting a successful compilation, but it's not printing any values.
class Space {
int one = 1;
int two = 2;
...
int ten = 10;
}
class green {
Space board = new Space[9][9];
for (int i = 0; i < board.length; i++) {
for (int j = 0; j < board[i].length; j++) {
board[i][j] = new Space();
System.out.println(board[i][j].one);
}
}
}

I think you can just refactor your Space class to just hold a primitive integer value:
class Space {
private int value;
private static final String MSG = "Space values must be between 1 and 10 inclusive";
public Space() { }
public Space(int value) {
// prevent spaces from being created with illegal values
if (value < 1 || value > 10) {
throw new IllegalArgumentException(MSG);
}
this.value = value;
}
public int getValue() {
return value;
}
}
Then, in your consuming class, use the Space class:
class Green {
private Space board = new Space[9][9];
for (int i=0; i < board.length; i++) {
for (int j=0; j < board[i].length; j++) {
// maybe get a value from somewhere and use it below
board[i][j] = new Space();
}
}
}
Regarding your exact question about values not printing, the bigger problem than above is that you don't have any logic for assigning values.
