Write a Java Program to Convert a List to Array and Vice Versa

import java.util.ArrayList;

class Main {
public static void main(String[] args) {
ArrayList languages = new ArrayList<>();

// Add elements in the list
languages.add(“Java”);
languages.add(“Python”);
languages.add(“JavaScript”);
System.out.println(“ArrayList: ” + languages);

// Create a new array of String type
String[] arr = new String[languages.size()];

// Convert ArrayList into the string array
languages.toArray(arr);
System.out.print(“Array: “);
for(String item:arr) {
System.out.print(item+”, “);
}
}
}

2: Convert Java Array to List

import java.util.Arrays;
import java.util.ArrayList;
import java.util.List;

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 list
List languages= new ArrayList<>(Arrays.asList(array));

System.out.println(“List: ” + languages);

}
}
