Apply function to all elements

Report a typo

You need to implement a method that applies the given function to all elements of the input array.

Do not create a new array, just change the elements of the original one.

Write a program in Java 17
import java.util.*;
import java.util.function.*;


public class Main {

public static <T> void applyFunction(T[] array, Function<T, T> func) {
// write your code here
}

// do not change code below
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String method = scanner.nextLine();
String[] array = scanner.nextLine().split(" ");
applyFunction(array,
"lower".equals(method) ? String::toLowerCase :
"upper".equals(method) ? String::toUpperCase :
"new".equals(method) ? String::new :
"trim".equals(method) ? String::trim : String::intern);
Arrays.stream(array).forEach(e -> System.out.print(e + " "));
}
}
