String replace in Android
<p>To try string replace in Android, I wrote a small snippet:</p>

<pre><code>public class cs{
 public static void main(String[] args){
   String a,c;
   int b;
   b=1;
   c="12345";
   a="12345,54321";
   a.replace(c，String.valueOf(b));
   System.out.println(a);
}
}
</code></pre>

<p><b>Expected Output:</b> 12345,54321 changes to 1,54321</p>

<p><b>Actual Output:</b> 12345，54321
。Please help。</p>
