What is mean by Anagram in Java?

How do you make an anagram in Java?

Anagram program in Java

  1. Step 1: Give input two strings.
  2. Step 2: Remove the spaces between words (if the string contains two or more words).
  3. Step 3: Create an array of chars for each string.
  4. Step 4: Sort the arrays.
  5. Step 5: If the sorted arrays are equal, the strings are anagrams, else they aren’t anagrams.

What is anagram in programming?

In other words, anagrams are a technique of C programming that checks whether a given string contains the same number of characters, except that the sequence of characters can be changed in both strings. For example, suppose we have two strings: “CAB” and “ABC”.

How do you find an anagram?

37 Answers. Two words are anagrams of each other if they contain the same number of characters and the same characters. You should only need to sort the characters in lexicographic order, and determine if all the characters in one string are equal to and in the same order as all of the characters in the other string.

How do you find the anagram of a string?

Method 2 (Count characters)

  1. Create count arrays of size 256 for both strings. Initialize all values in count arrays as 0.
  2. Iterate through every character of both strings and increment the count of character in the corresponding count arrays.
  3. Compare count arrays. If both count arrays are same, then return true.

What is anagram example?

An anagram is a word or phrase that’s formed by rearranging the letters of another word or phrase. For example, the letters that make up “A decimal point” can be turned into the anagram “I’m a dot in place.” … “Dormitory” turns into the anagram “dirty room,” and “snooze alarms” can be rearranged into “Alas!

Why is string final in Java?

The String is immutable in Java because of the security, synchronization and concurrency, caching, and class loading. The reason of making string final is to destroy the immutability and to not allow others to extend it. The String objects are cached in the String pool, and it makes the String immutable.

How many anagrams exist in a string?

Once occurrence ‘o’ of each frequency array is stored, total anagrams will be the sum of o*(o-1)/2 for all different frequency arrays because if a particular substring has ‘o’ anagrams in string total o*(o-1)/2 anagram pairs can be formed.

What are some good anagrams?

  3. static void isAnagram(String str1, String str2) {
  4. String s1 = str1.replaceAll(“\s”, “”);

Is permutation an anagram?

How do I print an anagram of a string?

A simple method is to create a Hash Table. Calculate the hash value of each word in such a way that all anagrams have the same hash value. Populate the Hash Table with these hash values. Finally, print those words together with same hash values.

How do you create permutations of a string?


  1. Define a string.
  2. Fix a character and swap the rest of the characters.
  3. Call the generatePermutation() for rest of the characters.
  4. Backtrack and swap the characters again.
