Advanced Java

It is also possible to generify the java.util.Set. Set instances in these cases might of a specific type.

Instances of that type in such cases could be inserted or read, from that set.

Usage of generic Set is explained here.

Java Code: This is the code to explain usage of generic Set

Set<String> set = new HashSet<String>;

Adding Elements to a Generic Set

To a set, specific String type is added by using this code.

Java Code: This is the code to add specific String type in a Set

Set<String> set = new HashSet<String>;
String string1 = "a string";
set.add(string1);

Iterating a Generic Set

To iterate over generic Set, use this code:

Java Code: This is the code to iterate over generic Set

Set<String> set = new HashSet<String>;
Iterator<String> iterator = set.iterator();
while(iterator.hasNext()){
  String aString = iterator.next();
}
