✐ Examples

1 Convert Array of Integers to Array of Strings

In this example,

Create an array of integers.
Convert the array to an IntStream using `Arrays.stream`.
Use the `mapToObj` function to convert each integer to a string.
Collect the converted strings into an array.

Java Program

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] intArray = {1, 2, 3, 4, 5};
        String[] stringArray = Arrays.stream(intArray)
                                      .mapToObj(String::valueOf)
                                      .toArray(String[]::new);
        System.out.println(String.join(", ", stringArray));
    }
}

Output

1, 2, 3, 4, 5
