Program to convert Set to List in Java
Let’s say the following is our Set with string values −
Set<String> set = new HashSet<String>();
set.add("Laptop");
set.add("Mobile");
set.add("Tablet");
set.add("LCD");
set.add("LED");Now, let us convert it to List −
List<String> list = new ArrayList<>(set);
Following is the program to convert Set to List in Java −
Example
import java.util.*;
import java.util.stream.*;
public class Demo {
public static void main(String args[]) {
Set<String> set = new HashSet<String>();
set.add("Laptop");
set.add("Mobile");
set.add("Tablet");
set.add("LCD");
set.add("LED");
set.add("Desktop");
System.out.println("Set = " + set);
List<String> list = new ArrayList<>(set);
System.out.println("List = " + list);
}
}Output
Set = [Laptop, Desktop, Tablet, LED, LCD, Mobile] List = [Laptop, Desktop, Tablet, LED, LCD, Mobile]
