String pattern = "##--user--##";
String replacement = "ny name";
int idx = -1;
while( ( idx = totalstring.indexOf( pattern ) ) >= 0 )
totalstring = totalstring.substring( 0, idx ) + replacement +
totalstring.substring( idx + pattern.length() );

Simple string substitution can be performed using indexOf() and some other
methods/classes. Here's an example utility method that can replace all
instances of a substring (toReplace) inside a given string (source) with a
replacement string (replacement).

public static String replaceAll(
String source,
String toReplace,
String replacement
) {
int idx = source.lastIndexOf( toReplace );
if ( idx != -1 ) {
StringBuffer ret = new StringBuffer( source );
ret.replace( idx, idx+toReplace.length(), replacement );
while( (idx=source.lastIndexOf(toReplace, idx-1)) != -1 ) {
ret.replace( idx, idx+toReplace.length(), replacement );
}
source = ret.toString();
}

return source;
}
