How can we escape the folder name having space in its name when passed from variable ?

I need to call a bat file from my Java program and the path of the bat file contains folder having spaces in its name. I am able to escape these folder name but the problem is that the path of the bat file is coming from a variable and I don't know how to escape the variable values.

Path of the bat file:- C:/My Data/batfile.bat My code to escape the space:

This works fine

String t = "C://\"My Data\"//BatFile.bat";
Process process=Runtime.getRuntime().exec("cmd /c start /wait "+t);

This doesn't work

String t = path+"//BatFile.bat";
Process process=Runtime.getRuntime().exec("cmd /c start /wait "+t);

path variable in above line contains the bat file path "C:/My Data"

Suggestions ?

You can do put it in quotes.

Process process=Runtime.getRuntime().exec("cmd", "/c", "start /wait \""+t+"\"");

Note: this doesn't work if the text also includes quotes, though a path shouldn't do so.
