关闭时是否存在现有FileInputStream删除？

标准库中没有这样的东西，也没有任何apache-commons库，所以类似：

public class DeleteonCloseFileInputStream extends FileInputStream {   private File file;   public DeleteonCloseFileInputStream(String fileName) throws FileNotFoundException{      this(new File(fileName));   }   public DeleteonCloseFileInputStream(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;         }       }   }}
