Hi Friend,

Try the following code:

class RemoveMultipleSpaces 
{
    public static void main(String[] args) 
    {
        String str = "Hello     World      How are     you?";
        String[] vals = str.split(" ");
        StringBuilder sb = new StringBuilder();
        for(String s : vals) { 
            if(s.trim().length() > 0){
                sb.append(s).append(" ");
            }
        }
        String out = sb.toString().trim();
        System.out.println(out);
    }
}

Thanks
