Write a java program to check two string is Anagram or not : 

import java.util.Scanner;

class Anagram {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.println("Enter first Sentence ");

String st=sc.nextLine();

int[] string1=indexNumber(st);

System.out.println("Enter Second Sentence ");

String st2=sc.nextLine();

int[] string2=indexNumber(st2);

CompareTwoArray ct=new CompareTwoArray();

boolean rs=ct.isAnagram(string1, string2);

if(rs) {

System.out.println("String is anagram ");

}

else {

System.out.println("Not a anagram");

}

}

static int[] indexNumber(String str) {

int count[]=new int[26];

for(int i=0;i<str.length();i++) {

char ch=str.charAt(i);

if(ch>=65 && ch<=90) {

count[ch-65]++;

}

else if(ch>=97 && ch<=122) {

count[ch-97]++;

}

}

return count;

}

}

public class CompareTwoArray {

static boolean isAnagram(int arr1[],int arr2[]) {

for(int i=0;i<arr1.length;i++) {

if(arr1[i]!=arr2[i]) {

return false;

}

}

return true;

}

}
