            .collect(Collectors.joining(" "));
    }
}

Another Solution

  class Solution {
      public String reverseWords(String s) {
          String[] arr = s.split(" ");
          String ans = "";
          for(int i=0;i<arr.length;i++) 
              ans += reverse(arr[i])+((i==arr.length-1)?"":" ");
          return ans;
      }
      static String reverse(String s){
          return new String(new StringBuffer(s).reverse());
      }
