What could be the java equivalent code for following php syntax:
$newPerson = array(
'firstname' => 'First',
'lastname' => 'Last',
'email' => '[email protected]',
);
I think here firstname is index of array and First is value at that index.How can I define such an array in java?
newPerson would be a java hash map (java.util.HashMap<String,String>) and you would explicitly insert by using put
Map<String, String> newPerson = new HashMap<String, String>();
newPerson.put("firstname", "First");
newPerson.put("lastname", "Last");
newPerson.put("email", "[email protected]");
I suspect the closest you'll come is a map:
Map<String, String> map = new HashMap<String, String>();
map.put("firstname", "First");
map.put("lastname", "Last");
map.put("email", "[email protected]");
EDIT: If you want to preserve insertion order (i.e. you need to know that firstname was added before lastname) then you might want to use LinkedHashMap instead.
Map<String, String> newPerson = new HashMap<String, String>()
{{
put("firstname", "First");
put("lastname", "Last");
put("email", "[email protected]");
}};
You should also use SortedMap to store value with user-define index name in sorted order
here is sample code to do this
define a SortedMap with:
SortedMap<String, String>newPerson = new TreeMap<String, String>();
to put value in shorted-map used:
newPerson.put("firstname", "First");
and to get this value :
newPerson.get(""firstname");
