java读取文本内容最后有个问号

[aJiaosu]

最后有个空格，为什么读取文本内容后再输出会有个问号

[十八道胡同]

你的代码咋写的？

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
 
 class Document {
     String filePath;
    public Document(String fileName) {   
        this.filePath=fileName;
    }
      public String getContent() {  
          File file=new File(filePath);
          StringBuilder result = new StringBuilder();
          try{
              BufferedReader br = new BufferedReader(new FileReader(file));
              String s = null;  
              while((s = br.readLine())!=null){
                  result.append(System.lineSeparator()+s);
              }
              br.close();    
          }catch(Exception e){ 
              e.printStackTrace();
          }
          return result.toString();
      }   
}
 
public class Main {
 
   public static void main(String[] args) {
      Document test=new Document("F:\\51060");
       System.out.println(test.getContent());
   }
}

引用 2 楼 qq_41006771的回复:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
 
 class Document {
     String filePath;
    public Document(String fileName) {   
        this.filePath=fileName;
    }
      public String getContent() {  
          File file=new File(filePath);
          StringBuilder result = new StringBuilder();
          try{
              BufferedReader br = new BufferedReader(new FileReader(file));
              String s = null;  
              while((s = br.readLine())!=null){
                  result.append(System.lineSeparator()+s);
              }
              br.close();    
          }catch(Exception e){ 
              e.printStackTrace();
          }
          return result.toString();
      }   
}
 
public class Main {
 
   public static void main(String[] args) {
      Document test=new Document("F:\\51060");
       System.out.println(test.getContent());
   }
}

我猜是换行符的关系？

BufferedReaderbr = new BufferedReader(new InputStreamReader(new FileInputStream(filePath), "UTF-8"));
