How can I perform operations on arrays in Java?

In Java, you can perform various operations on arrays such as sorting, searching, and modifying elements. What specific operation are you interested in?

Can you show me how to sort an array?

Sure! You can use the Arrays.sort() method to sort an array. For example:

int[] numbers = {5, 3, 8, 1};
Arrays.sort(numbers);

This will sort the array in ascending order.

What if I want to search for an element in the array?

You can use the Arrays.binarySearch() method to search for an element in a sorted array. Make sure the array is sorted before using this method.

Can you give me an example of searching for an element?

Of course! Here's an example:

int[] numbers = {1, 3, 5, 7, 9};
int index = Arrays.binarySearch(numbers, 5);

This will return the index of the element 5, which is 2.
