How to replace escape characters in a string ?

Question

Hi All,
In my application I came across a problem where I want to replace a substring (contains escape characters also) with another string. The below shown code will replicate my problem :
public class StringSearchAndReplace {
  public static void main(String args[])   {
    String stmt = " \\pntext\\bullet\\tab The question as to ";
    String newStmt = stmt.replaceAll("\\bullet\\tab",  "B");
    System.out.println("BEFORE: " + stmt + "\n");
    System.out.println("AFTER: " + newStmt);
}Here I want to replace "\\bullet\\tab" with "B". I am unable to move further. Please help/suggest me in this regard.
Its urgent.
Thanks in advance.

Thanks in advance.If the String you're trying to replace contains a slash you need four slashes (double it for java, then again because String.replaceAll takes a regular expression)
So I think what you're looking for is:
String newStmt = stmt.replaceAll("\\\\bullet\\\\tab",  "B");I haven't tested that though.
