An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. This Java program takes two strings as input and checks if they are anagrams of each other.

The solution approach is to first check if the lengths of the two strings are equal. If they are not, the function immediately returns false. If they are, the function converts both strings to lowercase and iterates through each character in the first string. For each character, it checks if it exists in the second string. If it does, it removes the first occurrence of that character from the second string. If it doesn't, it returns false. After iterating through all characters, if the second string is empty, it means all characters from the first string were found and removed from the second string, hence they are anagrams, and the function returns true.
