Java生活游戏实施：电路板更新和无限循环问题。

Question

Trying to make a Game of Life program. Having issues with loops and getting an accurate updating of the game board.

Sorry but I am a beginner so I'm not so good at this. any help is appreciated.

import java.util.Random;
  public class Life {
    public static void main(String[] args) {
      int gridSize = 200;
        int cellSize = 3;
        Grid grid = new Grid(gridSize, cellSize, "The Game of Life"); 
        grid.setDelay(10); 

        int aliveCells;
        int aliveColor = 1; 
        int deadColor  = 0;

        while (true) {
          for (column = 0;; column++) {
            for (row = 0;; row++) {
              grid.getPos(row, column);
              aliveCells = grid.matchingNeighbors(row, column, aliveColor);
              if (aliveCells == 2 || aliveCells == 3) {
                grid.setPos(row, column, aliveColor);
              } else {
                grid.setPos(row, column, deadColor);
              }
              grid.update();
            }
          }
        }

The comments show off the problem areas. Replace the CAPITAL TEXT with the appropriate variables/numbers.

import java.util.Random; public class Life { public static void main(String[] args) { int gridSize = 200; int cellSize = 3; Grid grid = new Grid(gridSize, cellSize, "The Game of Life"); grid.setDelay(10);

    int aliveCells;
    int aliveColor = 1; 
    int deadColor  = 0;

    //This creates a gridSizeXgridSize matrix, representing the board.
    int bufferBoard[][] = new int[gridSize][gridSize];

    while (true) {

      //Update the buffer board, represented by an matrix.
      for (int column = 0; column < gridSize; ++column) {
        for (int row = 0; row < gridSize; ++row) {
          int isAlive = grid.getPos(row, column); //Assigning current cell's alive-ness to variable to be used later.
          aliveCells = grid.matchingNeighbors(row, column, aliveColor);

          if(isAlive == aliveColor){ //Make all the checks for a living cell.
            if (aliveCells == 2 || aliveCells == 3) {
              bufferBoard[row][column] = aliveColor; //This cell will be alive.
            } else {
              bufferBoard[row][column] = deadColor; //This cell will be dead.
            }
          } else { //The current cell is dead.
            if(aliveCells == 3){
              bufferBoard[row][column] = aliveColor;
            }
          }
        }
      }

      //Time to populate the actual board.
      //Update the buffer board, represented by an matrix.
      for (int column = 0; column < gridSize; ++column) {
        for (int row = 0; row < gridSize; ++row) {
          grid.getPos(row, column);
          if (bufferBoard[row][column] == aliveColor) { //Check the location of the bufferBoard at the specified row and column. 
            grid.setPos(row, column, aliveColor);
          } else {
            grid.setPos(row, column, deadColor);
          }
          grid.update();
        }
      }
    }
