How to remove all null elements from a ArrayList or String Array?

Question

I try with a loop like that

// ArrayList tourists

for (Tourist t : tourists) {
    if (t != null) {     
        t.setId(idForm); 
    }   
}

Answer 1

This is easy way to remove default null values from arraylist

     tourists.removeAll(Arrays.asList(null));  

otherwise String value "null" remove from arraylist

       tourists.removeAll(Arrays.asList("null"));
