Java Question

How do I insert a word if the string has more than one space in Java?

I have the following code,

String s = " Hello I'm a multi spaced String"

In string s, there are multiple (indeterminate) spaces; but, I need to print it as
%temp%Hello I'm a%temp%multi spaced String

How can I do this?

Use regex \s{2,} and replaceAll() method like this:



%temp%Hello I'm a%temp%multi spaced String


public class HelloWorld
  public static void main(String[] args)
    String s = "    Hello I'm a       multi spaced String";
    s = s.replaceAll("\\s{2,}","%temp%");
