Write a Java program to check whether two strings are anagram or not? toLowerCase (). Also, the code can be optimized. At the end, I check if every key in the dictionary has a value of 0: if so, the number of chars in the first string 'cancel out' those in the second, which means the occurrences are equal and the strings are anagrams. Required fields are marked *. Two strings are said to be anagram, If both strings contain same characters, only the order of characters can be different. 2. // check if two strings are anagrams var areAnagrams = function(a, b) { // if length is not the same the words can't be anagrams if (a.length != b.length) return false; // make words comparable a = a.split("").sort().join(""); b = b.split("").sort().join(""); // check if each character match before proceeding for (var i = 0; i < a.length; i++) { if ((a.charAt(i)) != (b.charAt(i))) { return false; } } // all … If it is not zero(0) then the two string is not an anagram. Given two strings, determine if they are anagrams or not. Anagram : An anagram of a string is another string that contains same characters, only the order of characters can be different. Two strings are called anagrams if you can get the second string by rearranging all of the letters in the other string. Can the string contain duplicate characters? Method 2: Anagram Program in Java without using Array This is the primitive method to check if two Strings are Anagram, where we will be iterating each character of the first string and removing the particular character from the second string when found.
