Function that takes in an int array and returns a string array with all elements converted to strings

Trying to make a function that takes in an int[] numbers as input and returns a String[] with the values of numbers converted to Strings using the function. Not sure how to continue or how to convert ints to strings.

    int[] foo = ...
    String[] bar = new String[foo.length];
    for (int i = 0; i < foo.length; i += 1) {
        bar[i] = String.valueOf(foo[I];

    Next time you could probably google search too :)

    You can use Integer#toString to convert the integer to a string:

    int[] nums = ...;
    String[] stringNums = new String[nums.length]
    for(int i = 0; i < nums.length; i++){
        stringNums[i] = Integer.toString(nums[i]);
    return stringNums;

    Here's an alternative streams-based approach:

        int[] a = {1,2,3,4,5};
        String[] b = String[] b =[]::new);
    1. Make an IntStream containing the input data
    2. Convert to a stream of strings
    3. Convert to a String[]
