> string str=  "\\u0020"

think that should be:

String str=  "\u0020"

but the problem is that string is coming in a format "\\u0624c" I have to convert it \u0624c and then store it in a file

coming from where?

sounds like you'll need to manually decode it, something like:

char c = (char) Integer.parseInt(s.substring(3), 16);

i m using the following method to convert it:
but this method returns an extra "\" (backslash)
for example it should return \u0646 but it returns \\u0646

    //////////////////////////////////////////////////////////////////////////////////////////////////////////////
    public  String native2ascii(String s) {
        StringBuffer sb = new StringBuffer(s.length() + 80);
        for (int i = 0; i < s.length(); i++) {
            char c = s.charAt(i);
            //if (c <= 0xff) {
            if (c ==' ') {
                //  JOptionPane.showMessageDialog(null,String.valueOf(c),"if",1);
                sb.append("\\u0020" );
                //sb.append(c);
            } else {
                sb.append("\\u0" + Integer.toHexString((int) c).toUpperCase() );
                // JOptionPane.showMessageDialog(null,String.valueOf(c),"else",1);
            }
        }
        return sb.toString();
    }

Furthermore the following setProperty method is not workin correctly:

propertiesFile.setProperty("key","\\abc");

so it shuld set the value in property file as

key=\url

but it sets it as

key=\\url

WHY?

code looks fine, problem may be elsewhere
where exactly are you seeing the double slashes.

> key=\\url

again, where are you see this.
If its in the Properties file then it is correct, as the back slash must be escaped.

\abc is not a valid string as \a is not a defined escape sequence
