Java solution using BigInteger
```\n\nimport java.math.BigInteger;\nclass Solution {\n    public String kthLargestNumber(String[] nums, int k) {\n      BigInteger[] arr = new BigInteger[nums.
```\n\nimport java.math.BigInteger;\nclass Solution {\n    public String kthLargestNumber(String[] nums, int k) {\n      BigInteger[] arr = new BigInteger[nums.length];\n        for(int i=0;i<arr.length;i++){\n           arr[i]=new BigInteger(nums[i]);\n        }\n        Arrays.sort(arr);\n        BigInteger result= arr[arr.length-k];\n        return result.toString();\n    }\n}
