Java code that meets these requirments

Rotates the values in a character array left by the

* given number of positions, n, and saves it in a string.

* The first n characters are moved to

* the end of the string.

* Therefore, when done, the string has the same length

* as the given array.

*

* For example,

* rotate(['a', 'b', 'c', 'd'], 1) gives "bcda"  

* rotate(['a', 'b', 'c', 'd'], 3) gives "dabc"  

* rotate(['h', 'e', 'l', 'l', 'o'], 2) gives "llohe"  

You can assume that n is non-negative and

* less than the size of the array.

        String result = "";
        for (int i = 0; i < arr.length; i++)
            result = result + arr[(i+n)%arr.length];
        return result;
    }
  
    public static void main(String[] args) {
        char arr[] = {'a', 'b', 'c', 'd'};
        System.out.println("rotate(['a', 'b', 'c', 'd'], 1) is " + rotate(arr, 1));
        System.out.println("rotate(['a', 'b', 'c', 'd'], 1) is " + rotate(arr, 3));
        char arr1[] = {'h', 'e', 'l', 'l','o'};
        System.out.println("rotate(['h', 'e', 'l', 'l', 'o'], 1) is " + rotate(arr1, 2));
    }
}

This is the shortest code i could think of!! I hpe you like the code
