javaの読み込み.csvファイル：いくつかの行がありません

Question

私はRとJavaを使用しています。 Rを使用して、.csvファイルを作成しました。

write.table(allData,file="F:\\Project_file\\testgejavaedbyR1.csv",na="0.000001",sep=",",row.names = FALSE) 

このcsvファイルは次のようになります。

public void convertToArray(){ 
     int r=0; 
     // items = new String [CountRow()][9]; 
     items = new String [100][9]; 


     try{ 
      BufferedReader reader = new BufferedReader(new FileReader(file)); 
      String line= null; 

      while((line=reader.readLine()) !=null){ 
      line=reader.readLine(); 
      StringTokenizer z = new StringTokenizer(line,","); 
      while(z.hasMoreTokens()){ 
       for(int c=0; c<9; c++){ 
        items[r][c] = z.nextToken(); 
       } 
       r++; 
      } 
     } 
     }catch(Exception e){ 
      java.lang.System.out.println(e); 
     } 
    } 

    // print array now 

    public void printArray(){ 
     for(int x=0;x<items.length;x++){ 
      java.lang.System.out.printf("%s --- ",x); 
      // for(int y=0;y<items[x].length;y++){ 
       for(int y=0;y<9;y++){ 
       java.lang.System.out.printf("%s ",items[x][y]); 
      } 
      java.lang.System.out.println(); 
     } 
    } 

をしかしJavaで、私の出力は、ビット有線です：

私は、コードを使用してJavaでこのデータを印刷するtryinngよ各行の後に1行がありません 私のJava出力は：

Answer 1

あなたが二回ここのreadLineを行っている...

while((line=reader.readLine()) !=null){ 
     line=reader.readLine(); 

ちょうど二line=reader.readLine();
