java + replace small letters to capital letters in args
<p>Please advice:</p>

<p>I write here part of JAVA language 
in args[0] could be capital letters as "A" "B" "C" or small letter
 as "a" "b" "d" "i"</p>

<p>my target is to replace all small letters in args[0] to capital letters
How to do that?</p>

<p>The second question – how to remove spaces in args[0] ?</p>

<p>example
           args[0] could be deuSFRCQAAAVTvtev3843d4;'p-03eudhAHAHS</p>

<pre><code>       int[] anArray = new int[30];  

              anArray[0]= args[0].replaceAll("[^A]", "").length();
              anArray[1]= args[0].replaceAll("[^B]", "").length();
              .
              .
              .
              .
</code></pre>
