Copy all elements of Java LinkedHashSet to an Object Array
First, create a LinkedHashSet and add elements −
LinkedHashSet<String> l = new LinkedHashSet<String>();
l.add(new String("1"));
l.add(new String("2"));
l.add(new String("3"));
l.add(new String("4"));
l.add(new String("5"));
l.add(new String("6"));
l.add(new String("7"));Now, copy it to an object array like this −
// copying Object[] arr = l.toArray();
The following is an example to copy all elements of a LinkedHashSet to an object array −
Example
import java.util.*;
public class Demo {
public static void main(String[] args) {
LinkedHashSet<String> l = new LinkedHashSet<String>();
l.add(new String("1"));
l.add(new String("2"));
l.add(new String("3"));
l.add(new String("4"));
l.add(new String("5"));
l.add(new String("6"));
l.add(new String("7"));
System.out.println("LinkedHashSet elements...");
System.out.println(l);
// copying
Object[] arr = l.toArray();
System.out.println("Object Array: ");
for (Object res: arr){
System.out.println(res);
}
}
}Output
LinkedHashSet elements... [1, 2, 3, 4, 5, 6, 7] Object Array: 1 2 3 4 5 6 7
