class Solution {
    public String reverseWords(String s) {
        String[] array=s.split(" ");
        StringBuilder result=new StringBuilder();
        for(int i=0;i<array.length;i++){
            result.append(new StringBuilder(array[i]).reverse().toString()+" ");
        }
        return result.toString().trim();
    } 
}

Notes:

• Use String.split() function
• Use StringBuilder to reverse the String
• Use StringBuilder and append method is faster than use String
