java - 读入输入流后删除文件

Question

我正在尝试从本地存储的文件中检索视频流。读入输入流后，我试图删除该文件，但它不允许这种情况发生。我知道我需要关闭流，但我需要将此流传递给网络服务器调用。关于如何最好地解决这个问题的任何想法:

InputStream is = new FileInputStream("\\Location\\file.txt");
File f = new File("\\Location\\file.txt");

             if(f.delete()) {
                System.out.println("success");
             } else {
                System.out.println("failure");
             }  

Answer 1

尝试在 Finally block 上删除

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

class DeleteFile extends FileInputStream {

  File file;

  public DeleteFile(String s) throws FileNotFoundException {
    this(new File(s));
  }

  public DeleteFile(File file) throws FileNotFoundException {
    super(file);
    this.file = file;
  }

  public void close() throws IOException {
    try {
      super.close();
    } finally {
      if (file != null) {
        file.delete();
        file = null;
      }
    }
  }
}
