Java Program To Check two strings are Anagram or not [pdf]

Input Format:

The first line contains a string denoting A .
The second line contains a string denoting B.

Constraints:

• Strings A and B consist of English alphabetic characters.
• The comparison should NOT be case sensitive.

Output Format:

Print "Anagrams" if  A and  B are case-insensitive anagrams of each other; otherwise, print "Not Anagrams" instead.

Sample Input 1

anagram 
margana

Sample Output 1

Anagrams

Explanation:

Sample Input 2

anagramm
marganaa

Sample Output 2

Not Anagrams

Explanation:

The two strings don't contain the same number of a's and m's, so we print "Not Anagrams".

Sample Input 3

Hello
hello

Sample Output 3

Anagrams

Explanation :

The two strings contain all the same letters in the same frequencies, so we print "Anagrams".

Steps to be followed:

1. Take two Strings A and B as input.
2. Check length of both strings if not same then print Not anagram.
3. If length is same then create a flag variable 'k' .
4. Initialize 'k' to 0.
5. Create a loop i=0 - length of B.
6. For each value of i, find index of A.char(i) in B.
7. If a==-1 i.e not found set k=1 and break.
8. Else change A=A.substring(0,n)+A.substring(n+1)
9. Then print result according to value of 'k'.

        }
        else
            System.out.println("Not Anagrams");
    }
}
