Create an object array from elements of LinkedList in Java
An object array can be created from the elements of a LinkedList using the method java.util.LinkedList.toArray(). This method returns the object array with all the LinkedList elements in the correct order.
A program that demonstrates this is given as follows.
Example
import java.util.LinkedList;
public class Demo {
public static void main(String[] args) {
LinkedList<String> l = new LinkedList<String>();
l.add("Amy");
l.add("Sara");
l.add("Joe");
l.add("Betty");
l.add("Nathan");
Object[] objArr = l.toArray();
System.out.println("The object array elements are: ");
for (Object i: objArr) {
System.out.println(i);
}
}
}Output
The output of the above program is as follows −
The object array elements are: Amy Sara Joe Betty Nathan
Now let us understand the above program.
The LinkedList l is created. Then LinkedList.add() is used to add the elements to the LinkedList. A code snippet which demonstrates this is as follows
LinkedList<String> l = new LinkedList<String>();
l.add("Amy");
l.add("Sara");
l.add("Joe");
l.add("Betty");
l.add("Nathan");The LinkedList.toArray()method is used to convert the LinkedList into an object array objArr[]. Then the object array is displayed using a for loop. A code snippet which demonstrates this is as follows
Object[] objArr = l.toArray();
System.out.println("The object array elements are: ");
for (Object i: objArr) {
System.out.println(i);
}
