Subject Re: [lang] new functionality in StringUtils and ArrayUtils - proposal 01 - error
Date Sun, 23 Nov 2003 20:55:09 GMT
In my previous email,





  /**
   * <pre>
   * StringUtils.lead("abc", '.', 3)  = "abc..."
   */

This should be:

  /**
   * <pre>
   * StringUtils.trail("abc", '.', 3)  = "abc..."
   */
