Question

我有一个赋值，我必须在Java中对数组执行操作，我必须为每个操作创建单独的函数，我将编写但我无法弄清楚如何使用数组参数调用方法。我通常使用c ++编程，但这个任务是在java中。如果有人能帮助我，我会非常感激。：）

public class HelloJava {
    static void inpoot() {
        Scanner input = new Scanner(System.in);
        int[] numbers = new int[10];

        System.out.println("Please enter 10 numbers ");
        for (int i = 0; i < numbers.length; i++) {
            numbers[i] = input.nextInt();
        }
    }

    static void outpoot(int[] numbers) {
        for(int i = 0; i < numbers.length; i++) { 
                System.out.println(numbers[i]); 
        }
    }

    public static void main(String[] args) {
        inpoot();
        outpoot(numbers); //can not find the symbol
    }
}

Answer 1

您的inpoot方法必须返回int[]数组，然后将其作为参数传递给outpoot：

public class HelloJava {    
    static int[] inpoot() { // this method has to return int[]
        Scanner input = new Scanner(System.in);
        int[] numbers = new int[10];

        System.out.println("Please enter 10 numbers ");
        for (int i = 0; i < numbers.length; i++) {
            numbers[i] = input.nextInt();
        }
        return numbers; // return array here
    }

    static void outpoot(int[] numbers) {
        for(int i = 0; i < numbers.length; i++) { 
            System.out.println(numbers[i]); 
        }
    }

     public static void main(String[] args) {
        int[] numbers = inpoot(); // get the returned array
        outpoot(numbers); // and pass it to outpoot
    }
}
