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

May 7, 2022

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.

>Solution :

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;
