Java and windows – error: illegal escape character

I have finished changing registry data Java file But I'm running runtime getRuntime(). An illegal escape character error was encountered on the line of exec Where was my mistake?

import java.util.*;
import java.applet.Applet; 
import java.awt.*; 

class test {
  public static void main(String args[]) {
      try {
          Runtime.getRuntime().exec("REG ADD 'HKCU\Software\Microsoft\Internet Explorer\Main' /V 'Start Page' /D 'http://www.stackoverflow.com/' /F");
      } catch (Exception e) {
          System.out.println("Error ocured!");
      }
  }
}

Solution

You need the backslash used in the escape path

String windowsPath = "\\Users\\FunkyGuy\\My Documents\\Hello.txt";
