Usage

From source file:com.epam.catgenome.util.Utils.java

/**
 * Parses the original name of a file to remove its extension that matches the given one.
 * <p>//from  w w  w . j  a va  2s .  co m
 * It results in StringUtils.trimToNull() applied to <tt>fileName</tt> in the following
 * cases:
 * 1) <tt>fileName</tt> is <tt>null</tt> or consists of whitespaces only;
 * 2) <tt>extension</tt> is <tt>null</tt> or consists of whitespaces only;
 * 3) a call fileName.endsWith(extension) results with <tt>false</tt>; here both
 * <tt>fileName</tt> and <tt>extension</tt> are trimmed before checking.
 * <p>
 * Note:
 * It's expected <tt>extension</tt> starts with a dot that means e.g. '.txt' is correct,
 * but 'txt' is "illegal", because in such case the last dot won't be cut.
 *
 * @param fileName  {@code String} specifies the original filename including extension
 * @param extension {@code String} specifies the extension of a file that should be cut;
 *                  it should start with a dot - '.txt' is correct, 'txt' is illegal
 * @return {@code String}
