Yesterday I posted a question asking how to display a 2d array in JOptionPane. I did not really understand the code and I cant seem to update the table no matter what I do. I even tried without JOptionPane and it worked, I'm just so stumped as to what the problem is. All I want is for the cell in the array to change to an 'O' and for some reason it does'nt want to happen.
Here is my code (my indentation is a bit screwed thanks to stack overflow xD) :
import javax.swing.JOptionPane;
import javax.swing.*;
import java.util.*;
public class StarWars {
public static void main(String[] args) {
StringBuilder sb = new StringBuilder();
sb.append("<html>");
int column;
String [][] gridPlayer = new String [6][6];
Scanner kb = new Scanner (System.in);
String [] rows = {"A", "B", "C", "D", "E", "F", "G", "H"};
for (int i = 0; i < 6; i++){
for (int j = 0; j < 6; j++){
gridPlayer[i][j] = " ~ ";
}
}
sb.append("  ");
for (int i = 0; i < 6; i++){
sb.append(" " + rows[i] + " ");
}
sb.append("<br>");
for (int i = 0; i < 6; i++){
sb.append(" " + i);
for (int j = 0; j < 6; j++){
sb.append(gridPlayer[i][j]);
}
sb.append("<br>");
}
sb.append("</html>");
String answer = JOptionPane.showInputDialog(null, new JLabel(sb.toString()));
int rownum = 0;
String letter = answer.toUpperCase().substring(0,1);
for (int i = 0; i < rows.length; i++){
if (rows[i].equals(letter)){
rownum = i;
}
}
boolean gridUpdate = true;
while (gridUpdate == true){
String answer2 = "";
answer2 = answer.substring(1,answer.length());
column = Integer.parseInt(answer2);
gridPlayer[rownum][column] = " O ";
gridPlayer[3][4] = " D ";
gridPlayer[rownum][column] = answer;
if (gridPlayer[rownum][column].equals(" ~ ")){
gridPlayer[rownum][column] = " O ";
gridPlayer[3][4] = " D ";
gridUpdate = true;
}
JOptionPane.showInputDialog(null, new JLabel(sb.toString()));
}
}
}
