# Intuition\n<!-- Describe your first thoughts on how to solve this problem. -->\nThe code aims to determine if a given string **s** is an acronym formed by taking the first letter of each word in a list of strings **words**.\n# Approach\n<!-- Describe your approach to solving the problem. -->\n1. Iterate through each word in the **words** list and extract the first character of each word to form a new string **st**.\n2. Compare the string **st** with the input string s to check if they are **equal**.\n3. Return **true** if the strings match, indicating that **s** is an acronym; otherwise, return **false**.\n# Complexity\n- Time complexity:O(n)\n<!-- Add your time complexity here, e.g. $$O(n)$$ -->\n\n- Space complexity:O(n)\n<!-- Add your space complexity here, e.g. $$O(n)$$ -->\n\n# Code\n```Java []\npublic class Solution {\n    public boolean isAcronym(List<String> words, String s) {\n        int n = words.size();\n        StringBuilder st = new StringBuilder();\n        for (int i = 0; i < n; i++) {\n            st.append(words.get(i).charAt(0));\n        }\n        return s.equals(st.toString());\n    }\n\n}\n```\n```Java []\nclass Solution {\n    public boolean isAcronym(List<String> words, String s) {\n        StringBuilder sb=new StringBuilder();\n        for(String as:words){\n            sb.append(as.charAt(0));\n        }\n        return (s.equals(sb.toString()));\n    }\n}\n```\n\n```
