Set and List explanation
- Set – Stored elements in unordered or shuffles way, and does not allow duplicate values.
- List – Stored elements in ordered way, and allow duplicate values.
Set and List Example
import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
public class SetAndListExample
{
public static void main( String[] args )
{
System.out.println("List example .....");
List<String> list = new ArrayList<String>();
list.add("1");
list.add("2");
list.add("3");
list.add("4");
list.add("1");
for (String temp : list){
System.out.println(temp);
}
System.out.println("Set example .....");
Set<String> set = new HashSet<String>();
set.add("1");
set.add("2");
set.add("3");
set.add("4");
set.add("1");
set.add("2");
set.add("5");
for (String temp : set){
System.out.println(temp);
}
}
}

In Set, the stored values are in unordered way, and the duplicated value will just ignored.
Chutia… answerssssssss
Why is the list output not ordered?
It is ordered, it is not sorted. There is difference between sorted and ordered. Ordered means in the order in which the values were inserted.
