What are some common operations I can perform on arrays in Java?

In Java, common operations on arrays include searching, sorting, reversing, and merging arrays. Would you like examples of any specific operation?

Yes, 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 about searching for an element in an array?

You can use a linear search or binary search. For a linear search, you can loop through the array. For binary search, the array must be sorted first. Would you like to see code for both?

Yes, please provide the code for both search methods.

Here's how you can implement both:

Linear Search:

int search(int[] arr, int target) {
    for (int i = 0; i < arr.length; i++) {
        if (arr[i] == target) return i;
    }
    return -1;
}

Binary Search:

int binarySearch(int[] arr, int target) {
    int left = 0, right = arr.length - 1;
    while (left <= right) {
        int mid = left + (right - left) / 2;
        if (arr[mid] == target) return mid;
        if (arr[mid] < target) left = mid + 1;
        else right = mid - 1;
    }
    return -1;
}
