プログラムの出力をファイルに書き込む

Question

私は、pdfをテキストに解析するプログラムを書いています。イムはコンソールで出力を取得していますが、私はそれを艦隊に書き込めません。

public class PDFTextParser { 

public static void main(String args[]) throws IOException { 
    PDFTextStripper pdfStripper = null; 
    COSDocument cosDoc = null; 
    try { 


     File file = new File("1.pdf"); 
     PDDocument pdDoc = PDDocument.load(file); 
     pdfStripper = new PDFTextStripper(); 
     String parsedText = pdfStripper.getText(pdDoc); 
     System.out.println(parsedText); 
     FileWriter out = new FileWriter("output.txt"); 
     BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); 
     String line = in.readLine(); 
     while (line!= null) { 

       out.append(line); 
       out.append("\n"); 
       } 
     out.close(); 
    }catch (IOException e) { 
     e.printStackTrace();} 
    } 
} 

出力は次のとおりです：これは私が行っているコードです

Answer 1

を役に立てば幸いファイルに書き込むと、 残りのコードがユーザーからの入力を取得しようとします（例、キーボード） あなたは、必要な場合は、次のコードを使用してください：

String parsedText = pdfStripper.getText(pdDoc); 
System.out.println(parsedText); 
FileWriter out = new FileWriter("output.txt"); 
out.append(parsedText); 
out.close(); 

//no need for this code, it reads input from user (using keyboard) 
/* 
BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); 
String line = in.readLine(); 
while (line!= null) { 

     out.append(line); 
     out.append("\n"); 
     } 
out.close(); 
*/

この投稿をチェックアウトしましたか？私はあなたのケースでは、彼の最初の答え

java -jar myjar.jar > output.txt 

が好きしかしsystem-out-to-a-file-in-java

が

java -cp <classpath>/PDFTextParser > output.txt 

ようsomrthingことになるだけで、それはあなたがすでにPDFからテキストを持っている
