JAVA 把list集合换行写入文件

 1     for(int i = 0;i<array.size();i++){
 2             Goods g =  array.get(i);
 3              File file = new File("d://goodsInfo.txt");
 4               FileOutputStream fos1 = new FileOutputStream(file, true);
 5                 // 创建FileOutputStream对应的PrintStream，方便操作。PrintStream的写入接口更便利
 6                 PrintStream out1 = new PrintStream(fos1);
 7                 String str=""+g.getName()+","+g.getBarcode()+","+g.getPrice()+"\r\n";
 8                 out1.print(str);
 9                 out1.close();
10                 
11         }
