Ben metne pdf ayrıştırmak için bir program yazdım bir dosyaya

Question

içine bir programın çıktısını yazma. Çıkışı konsolda alıyorum, ancak bir filoya yazamıyorum.

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();} 
    } 
}

Answer 1

yardımcı olur umarım dosyaya yazmak, kod dinlenme kullanıcı (eski erkek klavye) Eğer don' dan girdi almak için trys t, sadece aşağıdaki kodu kullanın:

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(); 
*/

Bu gönderiyi kontrol ettiniz mi? Ben senin durumunda ilk cevabı

java -jar myjar.jar > output.txt 

gibi Ancak system-out-to-a-file-in-java

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

gibi somrthing olacağını sadece, zaten PDF metin var
