Tokenizer读取其他变量

Question

我从文件读取有大问题。我的在文件中的数据看起来像

8 
2 4 5 6 
1 3 4 8 
2 8 
1 2 6 8 
1 6 
1 4 5 7 8 
6 8 
2 3 4 6 7 

我想读8到变量n（n表示2D表尺寸：A [N] [N]）和休息值表。我写这篇文章，但代码工作很好，当我从文件中删除第一行（值8）和申报表的大小自己

import java.io.*; 
import java.util.StringTokenizer; 
class dfs 
{ 
private static PrintWriter zapis; 
static void przeszukiwanie_w_glab(int a[][], int m[], int i, int n) 
{ 
    int j; 
    System.out.println("\t" + (i+1)); 
    zapis.print((i+1)); 
    m[i] = 1; 
    for(j=0; j<n; j++) 
     if(a[i][j]==1 && m[j]==0) 
      przeszukiwanie_w_glab(a,m,j,n); 
} 
public static void main(String args[]) throws IOException 
    { 
     zapis = new PrintWriter("Out0204.txt"); 
     int n=8,i; 
     int m[]= new int[n]; 
     int a[][] = new int[n][n]; 
     for (i=0; i<n; i++) 
     { 
      m[i] = 0; 
     } 

     BufferedReader in = new BufferedReader(new FileReader("In0204.txt")); 
     String line; 
     for (int curLine = 0; (line = in.readLine()) != null; curLine ++) { 
      StringTokenizer tok = new StringTokenizer(line); 
      while (tok.hasMoreElements()) 
       a[curLine][Integer.parseInt(tok.nextToken()) - 1] = 1; 
     } 
     in.close(); 
     System.out.println("\nKolejnosc odwiedzanych wierzcholkow : \n"); 
     for (i=0; i<n; i++) 
      if (m[i]==0) 
      { 
       przeszukiwanie_w_glab(a,m,i,n); 
      } 
     zapis.close();   
    } 

}

不这项工作？：

public static void main(String args[]) throws IOException 
{ 

    BufferedReader in = new BufferedReader(new FileReader("In0204.txt")); 
    int n = Integer.parseInt(in.readLine()); 

    zapis = new PrintWriter("Out0204.txt"); 
    int i; 
    int m[]= new int[n]; 
    int a[][] = new int[n][n]; 
    for (i=0; i<n; i++) 
    { 
     m[i] = 0; 
    } 


    String line; 
    for (int curLine = 0; (line = in.readLine()) != null; curLine ++) { 
     StringTokenizer tok = new StringTokenizer(line); 
     while (tok.hasMoreElements()) 
      a[curLine][Integer.parseInt(tok.nextToken()) - 1] = 1; 
    } 
    in.close(); 
    System.out.println("\nKolejnosc odwiedzanych wierzcholkow : \n"); 
    for (i=0; i<n; i++) 
     if (m[i]==0) 
     { 
      przeszukiwanie_w_glab(a,m,i,n); 
     } 
    zapis.close(); 
} 

更重要的是，编码时请遵守Java命名约定。
