String.replaceAll not working, solution here

Sometime we get Exception in thread "main" java.util.regex.PatternSyntaxException during String.replaceAll() using.
When I used this code :

public void replaceString(String path){
System.out.println("Original Path :: "+path);
String ret = path.replaceAll("\\","/");
System.out.println("Return :: "+ret);
}
I got this exception
Exception in thread "main" java.util.regex.PatternSyntaxException: Unexpected internal error near index 1.

So for my project I am using this below custome method by the replaceAll method.


public void replaceString(String path){
System.out.println("Original Path :: "+path);
String ret = replaceAllString(path,"\\","/");
System.out.println("Return :: "+ret);
//return ret;
}
public String replaceAllString(String strOrig, String strFind, String strReplace) {
if(strOrig == null) {
return null;
}
StringBuffer sb = new StringBuffer(strOrig);
String toReplace = "";
if (strReplace == null) toReplace = "";
else toReplace = strReplace;
int pos = strOrig.length();
while (pos > -1) {
pos = strOrig.lastIndexOf(strFind, pos);
if (pos > -1) sb.replace(pos, pos+strFind.length(), toReplace);
pos = pos - strFind.length();
}
return sb.toString();
}

Its working fine for my project.
