Java简单的文件读写，换行

private static Vector<String> readFailures(String path) throws Exception{
Vector<String> failures = new Vector<String>();

FileReader fr = new FileReader(path);
BufferedReader bf=new BufferedReader(fr);
String temp = "";
while((temp = bf.readLine()) != null){
failures.add(temp);
}
bf.close();
fr.close();
return failures;
}
private static void writeFailures(String path, Vector<String> failures) throws Exception{
FileWriter fw = new FileWriter(path);
//		BufferedWriter bw=new BufferedWriter(fw);
for(int i=0;i<failures.size();i++)
{
String temp = failures.get(i);
fw.write(temp);
fw.write("/r/n");
}
fw.flush();
fw.close();
}
