What are some examples of arrays in Java?

In Java, an array is a collection of elements of the same type. For example, you can create an array of integers like this: int[] numbers = {1, 2, 3, 4, 5};.

Can you show me how to access elements in that array?

Sure! You can access elements using their index. For example, numbers[0] will give you the first element, which is 1.

What about multidimensional arrays?

Multidimensional arrays are arrays of arrays. For example, a 2D array can be declared like this: int[][] matrix = {{1, 2}, {3, 4}}; You can access elements using two indices, like matrix[0][1] which gives you 2.

Are there any built-in methods for arrays?

Yes! Java provides the Arrays class with methods like Arrays.sort() to sort arrays and Arrays.toString() to convert an array to a string representation.
