String - remove more than one space between words

[kri shan]

How can i remove more than one space between words ?
example My String k = " hai how are you". Wherever my String has more than one space, it should convert/reduce to one space between words. Here between (hai and how) and (are and you) has more than one space.

This will work. It may not be the best option, though.

String text = "This  is   a    test";
 
while(text.indexOf("  ") >= 0)
{
text = text.replaceAll("  ", " ");
}

With

text = text.replaceAll(" +", " ");

you won't need the loop any longer. "+" means "one or more of the preceeding character.

You can make it even more generic like this:

text = text.replaceAll("\\s+", " ");

which will replace multiple occurences of any whitespace char with a single space char.

i am using jdk 1.3. Jdk 1.3 doesn't support replaceAll(String,String)

Assuming you can't upgrade the version you are using, then you might like to look at a third party library like Jaklarta Regexp.

I browsed Jakarta Commons RegExp.How Jakarta RegExp helps ?

[Paul Sturrock]

Its a replacement for the regular expression support missing in pre-1.4 JDKs. You can use it to find the position of a pattern in a string. Once you know the position, you can replace it.

Take a look at the JavaDoc for replaceAll in JDK1.4. There is an example for alternative code that should give you a good idea of how to use JakartaRegex to achieve the same.
