Java Program to Convert the LinkedList into an Array and vice versa

Before you learn about the example, make sure you first visit the following tutorials,

• Java LinkedList Class
• Java Array
• LinkedList Data Structure

Example 1: Convert the LinkedList into Array

Output

LinkedList: [Java, Python, JavaScript]
Array: Java, Python, JavaScript,

In the above example, we have created a linked list named languages. Notice the line,

languages.toArray(arr);

Here, the toArray() method converts the linked list languages into an array. And stores it in the string array arr.

Note: If we don't pass any argument to the toArray() method, the method returns an array of the Object type.

Example 2: Convert Array to LinkedList

Output

Array: [Java, Python, C]
LinkedList: [Java, Python, C]

In the above example, we have created an array of String type. Notice the expression,

Arrays.asList(array)

Here, the asList() method of the Arrays class converts the specified array into the linked list.
