How can I perform various operations on arrays in Java?

In Java, you can perform operations like sorting, searching, and modifying arrays using built-in methods or loops.

Can you show me how to sort an array?

Sure! You can use Arrays.sort(array) to sort an array in ascending order. Here's an example: int[] arr = {5, 3, 8}; Arrays.sort(arr);.

What about searching for an element in an array?

You can use Arrays.binarySearch(array, key) for sorted arrays. For unsorted arrays, you might need to loop through the array.

How do I add an element to an array?

In Java, arrays have a fixed size. To add an element, you typically create a new array with a larger size and copy the elements over.
