翁恺java期末考试题

翁恺老师的期末考试题代码
class本来是自定义的但是不同过只能定义为Main
并且注释也无法识别会报错
这是最终提交通过的

 
import java.util.Scanner;
 
class Main
{
	private int times;
	private int width;
	private int height;
	int old_field[][];
	int new_field[][];
 
	Scanner in = new Scanner(System.in);
 
	void Init()
	{
		width = in.nextInt();
		height = in.nextInt();
		old_field = new int[height+2][width+2];
		new_field = new int[height+2][width+2];
		

		for (int i = 0; i < height+2; i++)
			for (int j = 0; j < width+2; j++)
			{
				old_field[i][j] = 0;
				old_field[i][j] = 0;
			}
		

		while(true)
		{
			int i=in.nextInt();
			int j=in.nextInt();
			if(i==-1&&j==-1)
				break;
			old_field[i+1][j+1]=1;
			new_field[i+1][j+1]=1;
		}

		times = in.nextInt();
	}
 
	void run()
	{

	}

	}
	void Test()
	{

		run();
		System.out.println(Count());
	}
	
	public static void main(String[] args)
	{
		// TODO Auto-generated method stub
		new Main().Test();
	}
