Write a Java Program to Convert the LinkedList into an Array and vice versa
PROGRAM: Java Program to Convert the LinkedList into an Array and vice versa
/*Java Program to Convert the LinkedList into an Array and vice versa*/
1: Convert the LinkedList into Array
import java.util.LinkedList;
class Main {
public static void main(String[] args) {
LinkedList<String> languages= new LinkedList<>();
// Add elements in the linked list
languages.add(“Java”);
languages.add(“Python”);
languages.add(“JavaScript”);
System.out.println(“LinkedList: ” + languages);
// Create a new array of String type
String[] arr = new String[languages.size()];
// Convert LinkedList into the string array
languages.toArray(arr);
System.out.print(“Array: “);
for(String item:arr) {
System.out.print(item+”, “);
}
}
}
2: Convert Array to LinkedList
import java.util.Arrays;
import java.util.LinkedList;
class Main {
public static void main(String[] args) {
// create an array
String[] array = {“Java”, “Python”, “C”};
System.out.println(“Array: ” + Arrays.toString(array));
// convert array to a linked list
LinkedList<String> languages= new LinkedList<>(Arrays.asList(array));
System.out.println(“LinkedList: ” + languages);
}
}
