Java method to return NULL as an empty String.

What if the String you are expecting comes back as null? Would it be the end of the world for you? Not if you have good exception handling. This method is also useful.

It will return an empty String “” of the String is null. If the String is not null, it will return the trimmed version of the Java String.

 private String getNullAsEmptyString(Object o){

        if( o instanceof String){
            if( o == null){
                return “”;
            return  o.toString().trim();

        return null;
