Answer 1

try this method and solve your doubts.

    Connection connection = DriverManager.getConnection(url, username, password);
    Statement stmt = connection.createStatement();
    ResultSet rs = stmt.executeQuery("SELECT col_blob FROM mysql_all_table");

    if (rs.next()) {
      Blob blob = rs.getBlob("col_blob");
      long blobLength = blob.length();

      int pos = 1; // position is 1-based
      int len = 10;
      byte[] bytes = blob.getBytes(pos, len);

      InputStream is = blob.getBinaryStream();
      int b = is.read();
