try this:

public static String replaceAll(String source, String toReplace, String replacement) {
                String lower = source.toLowerCase();
                String lowerReplace = toReplace.toLowerCase();
                // this code is written by David Hilsee
                int idx = lower.lastIndexOf( lowerReplace );
                if ( idx != -1 ) {
                        StringBuffer ret = new StringBuffer( source );
                        ret.replace( idx, idx+toReplace.length(), replacement );
                        while( (idx=lower.lastIndexOf(lowerReplace, idx-1)) != -1 ) {
                                ret.replace( idx, idx+toReplace.length(), replacement );
                        }
                        source = ret.toString();
                }
                return source;
        }

Hi objects,

ur method return the source all lower case letters and i don't want that, i need the method search the source string, find the match toReplace and do the replacement not to convert all source to lower case

for example

source: Google
to Replace: g
replacement: <font>g or G</font>
find letter g "capital or small letter" -- don't change it to small letter
final output String <font>G</font>oo<font>g</font>le

hope i make it clear

It doesn't convert it to all lower case, it just does case insensitive comparison
