Game of Life...HELP!

Posted 09 November 2009 - 09:42 AM

Hi, I've been trying to write the Game of Life code now for quite a while, and it's due today. My problem is that when I begin to do the sides of the 10x10 grid (where I wrote TOP, BOTTOM, RIGHT, LEFT) and then I tried to compile the program...I keep getting 20 errors all saying that "nbrcount [i][j] not a statement."

The rules of the game in my book are that if there is a dead cell and 3 live ones surrounding it, then that dead cell becomes alive. If there is a cell that is alive and it has one live neighbor, it dies. If there is a live cell with 3 or more cells surrounding, then it dies.

here is my extremely long and stupid code.

```public class Life{

public static void main(String[] args){

// BEGIN Random matrix

int nCols =10;
int nRows =10;
int generationNumber = 1;

int[][] cells = new int[nCols][nRows];
int[][] Ncount = new int[nCols][nRows];
int[][] newCells = new int[nCols][nRows];

sneeze(cells);

for(int i = 0;i<8;i++){

System.out.println("The " + i + " Generation is :"+"\n");
printArray(cells);
countNeighbors(cells,Ncount);
System.out.println("The Neighbor Count is:"+"\n");
printArray(Ncount);
death(cells,Ncount);
}

}

public static void setZeroes(int x[][]){
for(int i = 0;i<x.length;i++){
for(int j = 0;j<x[0].length;j++){

x[i][j] = 0;

}
}
}

public static void sneeze(int x[][]){
x[1][1]=1;
x[1][2]=1;
x[2][1]=1;
x[2][2]=1;
x[3][3]=1;
x[5][5]=1;
x[5][6]=1;
x[5][7]=1;

for(int i = 0;i<x.length;i++){
for(int j = 0;j<x[0].length;j++){

}
}
}

public static void countNeighbors(int cellx[][],int nbrcountX[][]){

setZeroes(nbrcountX);
for(int i = 1;i<cellx.length-1;i++){
for(int j = 1;j<cellx[0].length-1;j++){

if (cellx[i][j] == 1){
nbrcountX[i-1][j-1] ++;
nbrcountX[i-1][j] ++;
nbrcountX[i-1][j+1] ++;
nbrcountX[i][j+1] ++;
nbrcountX[i+1][j+1] ++;
nbrcountX[i+1][j] ++;
nbrcountX[i+1][j-1] ++;
nbrcountX[i][j-1] ++;

}

//TOP LEFT CORNER
if (cellx[0][0]==1){
nbrcountX[1][0]++;
nbrcountX[1][1]++;
nbrcountX[0][1]++;
}
//BOTTOM LEFT CORNER
if (cellx[9][0]==1){
nbrcountX[8][0]++;
nbrcountX[8][1]++;
nbrcountX[9][1]++;
}
//TOP RIGHT CORNER
if (cellx[0][9]==1){
nbrcountX[0][8]++;
nbrcountX[1][9]++;
nbrcountX[1][8]++;
}
//BOTTOM RIGHT CORNER
if (cellx[9][9]==1){
nbrcountX[8][9]++;
nbrcountX[9][8]++;
nbrcountX[8][8]++;
}
}
}

//TOP <------PROBLEM AREA FROM HERE TO RIGHT SIDE
for (int i=1; i < 9; i++){
if(cells[i][j]==1)
nbrcount[i-1][j];

if(cells[i][j]==1)
nbrcount[i-1][j+1];

if(cells[i][j]==1)
nbrcount[i][j+1];

if (cells[i][j]==1)
nbrcount[i+1][j+1];

if (cells[i][j]==1)
nbrcount[i+1][j];
}

//LEFT SIDE
for(int i=1; i < 9; i++){
if(cells[i][j]==1)
nbrcount[i][j+1];

if(cells[i][j]==1)

}

//BOTTOM SIDE

if(cells[i][j]==1)

if(cells[i][j]==1)
nbrcount[i][j-1];

nbrcount[i-1][j];

if(cells[i][j]==1)
nbrcount[i-1][j+1];

if(cells[i][j]==1)
nbrcount[i][j+1];
}

}

public static void death(int cells [][], int nbrCount[][]){

for(int j=0;j<nbrCount.length;j++){
for(int i=0;i<nbrCount[0].length;i++){

if(nbrCount[i][j]==1&&cells[i][j]==1){

cells[i][j]=0;
}

if(nbrCount[i][j]>3&&cells[i][j]==1){

cells[i][j]=0;
}
if(nbrCount[i][j]==3&&cells[i][j]==0){

cells[i][j]=1;
}

cells[i][j]=1;
}

if(nbrCount[i][j]==3&&cells[i][j]==1){

cells[i][j]=1;
}

}}}

public static void printArray(int b[][]){
for(int j=0;j<b.length;j++){
for(int i=0;i<b[0].length;i++){

System.out.print(b[i][j]+" ");
}
System.out.println();
}
System.out.println();

}
}

```

Ummm.. This is Javascript forum, Web Dev. language.
You need to ask this question in JAVA forum.

Good Luck.
