Damn java - got me again.

This problem asks us to return all words in a string(which can contain weird crap like numbers and symbols) that are longer than five letters in a new array.

Here is what I have so far:

public static String[] getBigWords(String sentence){  
  
         //sentence = sentence.replaceAll("\\d","");
        
         String [] temp = null;
         temp = sentence.split(" ");
       
         int size = 0;
         int k =0;
         for(int i = 0; i < temp.length; i++) {
          if(temp[i].length() > 5)
            size++;
         }
         
        String[] big = new String[size];
          for(int i = 0; i < temp.length; i++) {
          if(temp[i].length() > 5){
            big[k] = temp[i].toString(); 
            k++;}
           }
 return big;        
 }

I am getting the following errors:

Problems Detected:
*****⇒*****Word '67000120909' incorrrectly returned in result
*****⇒*****Word '6A7B0C0V0D1E2S0D9D09' incorrrectly returned in result
*****⇒*****Word 'location' not returned in result
*****⇒*****Word 'son-in-law' incorrrectly returned in result

Fails When:
*****⇒*****Long non letter strings
*****⇒*****Punctuation
*****⇒*****Punctuation, duplicate words, beginning/middle/end

--> Is there a regex expression that has everything but characters in it so I can place it in my replace function?

Thanks.

// at least n times
\w{5,}?

Or, possibly better now that I read your specs \S == pretty much anything except what you split the string on.

I don't understand,

I want to isolate char types only.
