问题 I am building this project in which I have to execute UNIX commands using ssh. Here is my question : When I execute the following command in a UNIX shell, echo "Hello World" It produces the output : Hello World With 5 spaces in between as the arguments were given within double quotes. I want to achieve the same effects with ssh as well.

The method will assemble the query string as is normally passed into the PreparedStatement , then simply replace each ? in the string with its corresponding single-quoted
