question about replace string

Hello,

i got a question about string replace.

e.g. the string: Life health Science IS Good for HEALTH

first: i want to search the word: "health", case insensitive, so "health" and "HEALTH" will be found.

then i want to replace "health" with health; HEALTH with HEALTH

so the string is: Life health Science IS Good for HEALTH

my question is, in order to replace and find the word "health", the string will be changed into lower case,
how i can get: Life health Science IS Good for HEALTH

instead of: life health science is good for health

Thanks so much for your reply,

Hi,

Please post your current codes.

the current code for replacement is like following :

=======================================

Sting testStr ="Life health Science IS Good for HEALTH";

String strPat ="HeaLth";

strPat =" " + strPat +" "; // add some leading and trailing space
testStr = " " + testStr + " ";

strReplace = " " + + strPat.toLowerCase() +;

if ( testStr.toLowercase().indexOf (strPat.toLowerCase()) != -1 ){

testStr = highlighStr(testStr.toLowercase(), strPat.toLowercase(), strReplace)

}

/* -- find the string and replace it with highligt --*/
String highlighStr(String source, String pattern, String replace)
{
if (source!=null)
{
final int len = pattern.length();
StringBuffer sb = new StringBuffer();
int found = -1;
int start = 0;

while( (found = source.indexOf(pattern, start) ) != -1) {
sb.append(source.substring(start, found));
sb.append(replace);
start = found + len;
}

sb.append(source.substring(start));

return sb.toString();
}
else return "";
}

Is this only for Upper case and Lower case issue only?

How if the string like
Life health Science IS Good for HealTH

Do you want it to be
Life health Science IS Good for HEALTH
or
Life health Science IS Good for HealTH

Hi, thanks for all replies. Well, I had to use the JDK 1.3, so I can't use replaceAll.

to suprapto45 : I agree with your suggestion that parameter "replace" is not necessary. i'm changing the code, will get back later.
