Question

Lets say I have string like this,

String sample = "This is a sample  string    with more than   two spaces in      a string   ";

Now what I have to do to make the string to have only one space between each word.
Thanks in advance.

Answer 1

If literally mean “space” then you can replace / {2,}/ with a single space. Note that a space in the regular expression matches a space in the text.

If by “space” you actually mean “all whitespace” (spaces, tabs, newlines, etc.), then use \s+ instead.
