Question

Need help with my code.... in line 50- Public static void diplaycells(int data[]) there is an error that says it has an illegal start of expression! i dont know what to do to fix it.

public static void main(String[] args) {
    {Scanner in=new Scanner(System.in);
int n,i,steps;
System.out.println("Welcome to the cellular automaton simulation!");
System.out.print("Enter number of cells (<= 80): ");
n=in.nextInt();
while(n<1||n>80)
     {System.out.println("invalid length");
        System.out.print("Enter number of cells (<= 80): ");
       n=in.nextInt();
        }
int []cells=new int[n];
for(i=0;i<n;i++)
     cells[i]=0;
System.out.print("Enter number of time steps: ");
steps=in.nextInt();
System.out.print("Enter the index of occupied cells (negative index to end): ");
i=in.nextInt();
while(i>=0)
{if(i<n)
       cells[i]=1;
   i=in.nextInt();
    }
System.out.println();
for(i=0;i<n;i++)
   System.out.print(i%10);
System.out.println();
System.out.println();
displayCells(cells);
for(i=0;i<steps;i++)
     {updateCells(cells);
    displayCells(cells);
    }
}

public static void displayCells(int data[])
{int i;
for(i=0;i<data.length;i++)
   if(data[i]==0)
        System.out.print(" ");
    else
System.out.print("#");
System.out.println();
}
public static void updateCells(int a[])
{int n,i;
n=a.length;
int []t=new int[n];
t[0]=a[0];
t[n-1]=a[n-1];
   for(i=1;i<n-1;i++)
        t[i]=1;
    for(i=1;i<n-1;i++)
        if((a[i-1]==1&&a[i]==1&&a[i+1]==1)||
            (a[i-1]==1&&a[i]==0&&a[i+1]==0)||
            (a[i-1]+a[i]+a[i+1]==0))
                 t[i]=0;
    for(i=0;i<n;i++)
       a[i]=t[i];

}
}

Explanation / Answer

Length is a function, not a property

public static void displayCells(int data[])
{int i;
for(i=0;i<data.length();i++)
   if(data[i]==0)
        System.out.print(" ");
    else
System.out.print("#");
System.out.println();
}
