從Eclipse將控制檯消息寫入文件

Question

如何將Eclipse的控制檯消息寫入文件？

請檢查它，如果任何人提供解決方案，我將不勝感激。 我的示例程序如下

給出的是這樣的控制檯消息：

Invalid Excel Path Specified "+path 

---

 try {      
      BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); 
      String lineFromInput = in.readLine(); 

      PrintStream out = new PrintStream(new FileOutputStream("C:/Error.txt"));    
      System.setOut(out);  
         out.close(); 
     } 
      catch(IOException e1) { 
      System.out.println("Error during reading/writing"); 
     }  
    } 

Answer 1

您需要更改 FileOutputStream("C:/Error.txt")

到

FileOutputStream("C:\\Error.txt")

Juned Ahsan提到。除此之外，如果你需要寫你從控制檯進入

Error.txt

文本需要後

System.setOut(out);

線，在哪裏添加一行

System.out.println(lineFromInput);您設置默認的輸出位置。

Answer 2

PrintStream out = null; 
     try { 
      BufferedReader in = new BufferedReader(new InputStreamReader(
        System.in)); 
      String lineFromInput = in.readLine(); 

      out = new PrintStream(new FileOutputStream("C:/Error.txt")); 
      System.setOut(out); 
      System.out.println(lineFromInput); 
     } catch (IOException e1) { 
      e1.printStackTrace(); 
      System.out.println("Error during reading/writing"); 
     } finally { 
      if (out != null) { 
       try { 
        out.close(); 
       } catch (Exception e) { 
        //ignore 
       } 
      } 
     }
