Answer 1

Using Google's guava library

String[] firstArray = {"test1","","test2","test4","",null};

Iterable st=Iterables.filter(Arrays.asList(firstArray),new Predicate() {
    @Override
    public boolean apply(String arg0) {
        if(arg0==null) //avoid null strings 
            return false;
        if(arg0.length()==0) //avoid empty strings 
            return false;
        return true; // else true
    }
});
