## Can we use insertion sort on strings?

The logic of sorting integer array using the insertion sort algorithm is inside method insertionSort(int[]). In Java you can also sort any object e.g. String using this algorithm, all you need to do is to use a Comparable interface because that will provide you mechanism to compare two objects.

**How do you sort a string array in Java?**

To sort a String array in Java, you need to compare each element of the array to all the remaining elements, if the result is greater than 0, swap them.

**Can arrays sort sort strings?**

1. Sort array of strings using Arrays. sort() method. It sorts the specified array of strings into ascending order, according to the natural ordering of its elements.

### How the insertion sort is done with the array?

Working of Insertion Sort

- The first element in the array is assumed to be sorted. Take the second element and store it separately in key .
- Now, the first two elements are sorted. Take the third element and compare it with the elements on the left of it.
- Similarly, place every unsorted element at its correct position.

**When insertion sort is a good choice for sorting an array?**

Explanation: The insertion sort is good for sorting small arrays. It sorts smaller arrays faster than any other sorting algorithm.

**How do you sort a string array in Java without using the sort method?**

Basically String class do not have method to sort string array. So to sort string array we need to match each element of an array to the remaining elements. To do that we are using nested for loop. Inner for loop avoid duplicates in comparison and starts from a + 1, where “a” is variable of “outer for loop”.

#### How do you sort an array of strings in ascending order?

Sort String Array in Ascending Order or Alphabetical Order

- import java.util.Arrays;
- public class SortStringArrayExample2.
- {
- public static void main(String args[])
- {
- //defining an array of type string.

**Can you sort an array in Java?**

Using the sort() Method In Java, Arrays is the class defined in the java. util package that provides sort() method to sort an array in ascending order. It uses Dual-Pivot Quicksort algorithm for sorting.

**What is the best case for insertion sort?**

n

Insertion sort/Best complexity

So, if every element is greater than or equal to every element to its left, the running time of insertion sort is Θ(n)\Theta, left parenthesis, n, right parenthesis. This situation occurs if the array starts out already sorted, and so an already-sorted array is the best case for insertion sort.

## What is an example of insertion sort?

Insertion sort is a simple algorithm for sorting an array

**How is insertion sort better than bubble sort?**

Difference Between Bubble Sort and Insertion Sort Definition. Bubble sort is a simple sorting algorithm that repeatedly goes through a list, comparing adjacent pairs and swapping them if they are in the wrong order. Functionality. Number of swaps. Speed. Complexity. Conclusion.

**What is insertion sort?**

Insertion sort is another sorting algorithm, which operates by inserting an element in the input list in to the correct position in a list (that is already sorted). This process is applied repeatedly until the list is sorted. In insertion sort, sorting is carried out in-place.

### How efficient IS insertion sort?

Insertion Sort. Running time is an important thing to consider when selecting a sorting algorithm since efficiency is often thought of in terms of speed. Insertion sort has an average and worst-case running time of O (n2), so in most cases, a faster algorithm is more desirable.
