Вертикальная печать с java массивов

Question

У меня проблемы с кодом именно с массивами. У меня проблемы с вертикальной печатью массивов. Единственный способ, который я мог придумать, - это использовать один полный массив, но у вас не может быть значений string и int в одном массиве.

Я не уверен, что мне нужно сделать, чтобы исправить проблему с печатью в Это дело. Я просматривал код несколько раз и не мог его понять.

//imports scanner object

Answer 1

1. Вы можете использовать Object-Arrays (Object [] []) для хранения в нем любых данных, которые также включают строки, целые числа, числа с плавающей запятой и т. Д. c.

2. Вы можете распечатать эти массивы с помощью циклов for, где вам не нужны отдельные счетчики

3. Реализация:

publi c class Test {

// in this array you can input any Number/String/Objects
public static Object list[][] = new Object[5][20]; // <-- just change dimensions here

public static void main(String[] args) {
    //
    // this part is just here to randomly fill the array
    for (int i = 0; i < list.length; i++) {
        for (int j = 0; j < list[i].length; j++) {

            int rand = (int) (Math.random() * 2);
            switch (rand) {
            case 0:
                list[i][j] = "A"; // example
                break;
            case 1:
                list[i][j] = 1; // example
                break;
            }
        }
    }
    //
    
    print_Y_X();
    System.out.println(); // free line
    print_X_Y();
}

// for printing the array, where every line represents the first dimension of the array
public static void print_X_Y() {
    
    String spacing = " "; // spacing between the arrayobjects
    
    for(int i=0;i<list.length;i++) {
        System.out.print("[ "); // Line-start
        for(int j=0;j<list[i].length;j++) {
            System.out.print(list[i][j]+(j != list[i].length-1 ? spacing : ""));
        }
        System.out.println(" ]"); // Line-end
    }
}

// for printing the array, where every line represents the second dimension of the array
public static void print_Y_X() {
    
    String spacing = " "; // spacing between the arrayobjects

    for(int j=0;j<list[0].length;j++) {
        System.out.print("[ "); // Line-start
        for(int i=0;i<list.length;i++) {
            System.out.print(list[i][j]+(i != list.length-1 ? spacing : ""));
        }
        System.out.println(" ]"); // Line-end
    }
}

}
