我正在爲康威的一個學校項目的生命遊戲工作。我不直接尋找代碼。我正在查找我的代碼出了什麼問題。JAVA - 康威的生命遊戲會刪除所有活細胞？
在康威的生命遊戲中，如果一個細胞擁有3個活着的鄰居，它就會從死亡到活着。如果它有兩三個活着的鄰居，它就會保持活力。如果這些都不是真的，它就是死的。
我的LifeView類有一個方法，顯示細胞模擬，然後顯示有多少活細胞在給定點周圍。
這是我得到的輸出：
How many rows is your simulation?
5
How many columns is your simulation?
5
How many generations is your simulation?
3

這是錯誤的，因爲第二代應該是活細胞穿越了第一代的活細胞中心的水平線。不是穿過那個中心，所有的細胞都會死亡。我很難理解爲什麼它不起作用。
主類：
package gameOfLife;
import java.util.Scanner;
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
Scanner numReader = new Scanner(System.in);
System.out.println("How many rows is your simulation?");
int rows = numReader.nextInt();
System.out.println("How many columns is your simulation?");
int columns = numReader.nextInt();
System.out.println("How many generations is your simulation?");
int generations = numReader.nextInt();
LifeModel model = new LifeModel(rows,columns);
LifeView life = new LifeView(model);
for(int i=0; i<generations; i++)
{
life.displayLife();
model.nextGeneration();
}
}
朗視類：
package gameOfLife;
import java.util.Scanner;
public class LifeView {
private LifeModel model;
public LifeView(LifeModel model)
{
this.model = model;
}
public void displayLife()
{
for(int i=0; i < model.getWorld().length; i++)
{
for(int j=0; j < model.getWorld()[0].length; j++)
{
if(model.getWorld()[i][j])
{
System.out.print("0");
}
else
{
System.out.print("x");
}
}
System.out.println("");
}
System.out.println("");
for(int i=0; i < model.getWorld().length; i++)
{
for(int j=0; j < model.getWorld()[0].length; j++)
{
System.out.print(model.numLivingNeighbors(i,j));
}
System.out.println("");

LifeModel類： 包gameOfLife;

public void nextGeneration()

int rows = world.length;
int columns = world[0].length;
for(int i=0; i < rows; i++)

}
public void toggleCell(int r, int c)

任何幫助非常感謝！
