java - Java将数据写入外部文件

Question

我的 BufferedReader 中有数据，但我想在外部文件中打印数据。我该怎么做？

    URL url=new URL(input);
    BufferedReader br=new BufferedReader(new InputStreamReader(url.openStream()));
    String inputLine;
    while((inputLine=br.readLine())!=null)
        System.out.println(inputLine);
    br.close();

上面的代码对我有用。相反，我想将数据保存在外部文件中。

Answer 1

URL url=new URL(input);
BufferedReader br=new BufferedReader(new InputStreamReader(url.openStream()));
String inputLine;
BufferedWriter writer = Files.newBufferedWriter(Paths.get(""));
while ((inputLine = br.readLine()) != null) {
   System.out.println(inputLine);
   writer.write(inputLine);
   // must do this: .readLine() will have stripped line endings
   writer.newLine();
   }
writer.close();
br.close();
