Java array indexing. How to avoid cycles?

Question

Java

public class Main {
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        String str = sc.next();
        char[] array = str.toCharArray();

        //выводы (костыли на циклах)
        char third_symbol = array[2];
        char pre_last_symbol = array[array.length - 2];

        System.out.print(third_symbol + "\n" + pre_last_symbol + "\n");
        // вывод первых пяти символов
        for (int i = 0; i < 5; i++) {
            System.out.print(array[i]);;
        }
        System.out.println(); // перенос строки просто

        //вывод строки без последних двух символов
        for (int i = 0; i < array.length-2; i++) {
            System.out.print(array[i]);
        }
        System.out.println(); // перенос строки просто

        //вывод строки без первых трёх символов
        for (int i = 3; i < array.length; i++) {
            System.out.print(array[i]);
        }
        System.out.println(); // перенос строки просто

        //вывод длины строки
        System.out.print(array.length);
    }
}

Good afternoon.
If I were you, I would do the following:
I would create a method that takes several arguments:
1) the array itself, over which you need to
iterate 2) startOffset is if you need to output char without the first n characters
3) endOffset is if you need to output char without the last n characters
Or you can implement something similar using the Stream API. But most likely you are still learning Java and most likely you haven't gotten there yet...
