使用 Buffered Writer 时，输入的文本未完全写入文件

Question

下面是我使用 BufferedWriter 将文本写入文件的代码：

        public class InputOutputStream {

          public static void main(String[] args) 
         {                
         FileReader f = null;
         File fu = new File("C:\Akki.txt");    
         BufferedReader f1 = null;
         FileWriter f2 = null;
         BufferedWriter f3 = null;

            try{
             String s1;
             f = new FileReader("C:\Test.txt");
             f1 = new BufferedReader(f);
             while((s1 = f1.readLine())!=null)
             {
            System.out.println(s1);
             }

     //User enters the content and same is written to file

         f2 = new FileWriter(fu, true);
         f3 = new BufferedWriter(f2);

      System.out.println("Enter the text to write in File");

        Scanner sc = new Scanner(System.in);
        String k = sc.next();
        f3.write(k);

        f3.flush();
        f3.close();     
       }
    catch(IOException e)
    {
        System.out.println("IOException");
    }
    finally
    {
        if(f1!= null)
        try{                
            f1.close();
        }
        catch(IOException e)
        {
            e.printStackTrace();
        }
      }

   }

}

现在，当我输入如下文本时：“测试数据写入成功” 只有 'Test' 正在写入，其余字符串未写入

请帮忙

不是因为作家。这是因为Scanner。你用next，试试nextLine

使用 Buffered Writer 时，输入的文本未完全写入文件

Entered Text is not completely written in file when using Buffered Writer

java
