What does sorting an array means?

1. import java. util. Arrays;
2. public class Sorting {
3. public static void main (String [] args) {
4. int [] array = {45,12,85,32,89,39,69,44,42,1,6,8};
5. Arrays. sort(array);
6. System. out. println(“Completely Sorted: ” + Arrays.
7. int index = Arrays. binarySearch(array, 42);
8. System. out.

What is an array and why do we use it?

An array is a data structure, which can store a fixed-size collection of elements of the same data type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

What is sorted and unsorted array?

In short, searching in an unsorted array takes O(n) time: you potentially have to look at every item to find out if what you’re looking for is there. A sorted array lets you speed up the search. Instead of having to examine every item, you only have to examine at most log2(n) items.

Is array sorted?

The idea is to loop over the array and compare each element to its successor. Now for any pair of consecutive elements, the array is considered unsorted if the first element is found to be more in value than the second element. The array is considered sorted if we have reached the end of the array.

What is sorting in Java?

Sorting is the process of putting a list or a group of items in a specific order. Sorting can also be done in ascending order (A-Z) or descending order (Z-A). Sorting refers to ordering data in an increasing or decreasing fashion according to some linear relationship among the data items.

What is an array with example?

How to merge two sorted arrays?

– Start – Declare two arrays and initialize them. – Declare a sort function that will sort the array elements in ascending order. – After initializing the first two arrays, call the sort function. – Now, merge the two arrays. – Again, call the sort function. – Print the resultant sorted array. – End

How do you merge two sorted arrays?

You enter two short sorted arrays and combine them to get a larger array. If the arrays are not sorted then you can sort them first and then use the merge function, another method is to merge them and then sort the array.
