Hi,

public int wordsCount(String[] words, int len) {
int count=0;
for(int i=0;i<words.length;i++){
  if(words[i].length()==len){
    count++;
    
  }
  
  
}
return count;
  
}

You didn't link to the problem but I can pretty much deduce the requirements from the code. I wouldn't have done anything different to what you have done.

Only a slight modification to what you have done -
int count = 0;
for (String word : words) {
  if (word.length == len) {
    count++;
  }
}
return count;

That's a modification. But is it an improvement?
Also, only advisable when gudii9 is working with Java 8

It wasn't meant as an improvement. I was only trying to show gudii9 an alternate means of looping through an array other than incrementing an index.

It's good that that is cleared out now. Since he asked for improvements.

Correction: my remark about Java 8 is incorrect.

That gives you an indentation of 1 space. Which is better than nothing.
But that's not what you posted.

How to indent codingbat code without starting eclipse which some times takes time?
By indenting by hand (= adding 4 spaces). It's so worth the effort. You gain readability for yourself and us.

Concerning your real question: there's nothing to improve.
