String selectedVal = "";

for (SelectItem item : filterItems) {
                selectedVal = item.getValue().toString();

I try to use if (! Selectedval. Equals ("") and if (! Selectedval. Isempty()) but the condition becomes true How do I check multiple spaces?

Solution

You can trim () strings before checking with isempty()

boolean isEmpty = myString.trim().isEmpty();

Beware of isempty (), which is only available after Java se 6
