===Using FileNameExtensionFilter===
{{works with|Java|6+}}
This version is the same as the main version only replace the definition for <code>extIsIn</code> with:
<lang java5>public static boolean extIsInFF(String test, String... exts){
for(int i = 0; i < exts.length; i++){
exts[i] = exts[i].replaceAll("\\.", "");
}
return (new FileNameExtensionFilter("extension test", exts)).accept(new File(test));
}</lang>
It would be one line if not for the dot requirement. <code>FileNameExtensionFilter</code> requires that the extensions have no dots. It also requires that the extensions contain characters (i.e. not the empty string) so that test would need to be removed.
