## What is sorting in array explain with an example?

A sorted array is an array data structure in which each element is sorted in numerical, alphabetical, or some other order, and placed at equally spaced addresses in computer memory. It is typically used in computer science to implement static lookup tables to hold multiple values which have the same data type.

## How do you sort an array and search an element inside it?

Java Program to Search Key Elements in an Array

1. import java.util.Scanner;
2. public class Search_Element.
3. {
4. public static void main(String[] args)
5. {
6. int n, x, flag = 0, i = 0;
7. Scanner s = new Scanner(System. in);
8. System. out. print(“Enter no. of elements you want in array:”);

How do you arrange numbers in ascending order in Java?

Algorithm

1. STEP 1: START.
2. STEP 2: INITIALIZE arr[] ={5, 2, 8, 7, 1 }.
3. STEP 3: SET temp =0.
4. STEP 4: PRINT “Elements of Original Array”
5. STEP 5: REPEAT STEP 6 UNTIL i
6. STEP 6: PRINT arr[i]
7. STEP 7: REPEAT STEP 8 to STEP 9 UNTIL i
8. STEP 8: REPEAT STEP 9 UNTIL j

What is best sorting algorithm?

The time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

### How many types of sorting are there in Java?

5 Popular Sorting Algorithms in Java Merge Sort. Heap Sort. Insertion Sort. Selection Sort.

### How do I find a sorted array?

Given a sorted array of integer numbers, write a function which returns zero-based position on which the specified value is located. Function should return negative value if requested number cannot be found in the array. If value occurs more than once, function should return position of the first occurrence.

What are different ways to sort an array in Java?

Java provides the following methods to sort the arrays. Using For Loops: You can use for loops to traverse the array and compare adjacent elements while traversing and putting them in order. Using The Sort method: The Arrays class of ‘java.util’ package provides the sort method that takes an array as an argument and sorts the array.

How do I sort a string in Java?

Sort a String in Java (2 different ways) String class doesn’t have any method that directly sort a string, but we can sort a string by applying other methods one after other. Method 1(natural sorting) : Apply toCharArray() method on input string to create a char array for input string.

#### What is Array sort?

Array sorting is the process of taking the individual elements of an array and arranging them in some type of logical order according a series of rules defined by the user.

#### What is array of integers?

An integer array is a set of integers or “whole numbers” used for various computational purposes. An integer is a number that does not include a fraction. Integers include both positive and negative whole numbers, such as zero, one, and negative one. An integer array is just a set of these numbers defined in mathematics or computer programming.
