Kotlin program to check whether two strings are anagram of each other

Kotlin | Check anagram strings: Here, we are going to learn how to check whether two strings are anagram of each other in Kotlin programming language?

What is anagram?

An anagram is a string that can be formed by rearranging the characters of a different string using all the original characters exactly once.

For example, "anagram" can be rearranged into "nag a ram", "binary" can be rearranged into "brainy".

Given two strings, we have to check whether they are anagram of each other.

Example:

    Input:
    String1 = "binary"
    String2 = "brainy"

    Output:
    True
    Both are anagram strings

Program to check whether two strings are anagram of each other in Kotlin

package com.includehelp.basic

import java.util.*


/**
 * Function to check two strings are anagram string or not
 */
fun isAnagrams(str1: String, str2: String): Boolean {
    //Both String Length must be Equal
    if (str1.length != str2.length) {
        return false
    }

    //Convert Strings to character Array
    val strArray1 = str1.toCharArray()
    val strArray2 = str2.toCharArray()

    //Sort the Arrays
    Arrays.sort(strArray1)
    Arrays.sort(strArray2)

    //Convert Arrays to String
    val sortedStr1 = String(strArray1)
    val sortedStr2 = String(strArray2)

    //Check Both String Equals or not After Sorting 
    //and Return value True or False
    return sortedStr1 == sortedStr2
}

//Main Function, entry Point of Program
fun main(args: Array<String>) {
    //Input Stream
    val sc = Scanner(System.`in`)

    //Enter String Value
    println("Enter String1 : ")
    val str1: String = sc.nextLine()

    println("Enter String2 : ")
    val str2: String = sc.next()

    //Call Function to  check anagram String
    if (isAnagrams(str1, str2)) {
        println("Anagram Strings !!")
    } else {
        println("Strings are not Anagram !!")
    }
}

Output

Run 1:
Enter String1 :
raghu
Enter String2 :
gharu
Anagram Strings !!
---
Enter String1 :
Hello
Enter String2 :
includehelp
Strings are not Anagram !!
---
Enter String1 :
john
Enter String2 :
hnoj
Anagram Strings !!
