Answer

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

s.replaceAll("\\s{2,}","%temp%");

Output

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

Code

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