題目

從命令列讀入兩個陣列的長度和陣列的值，其中第一行兩個數na和nb代表aa和bb陣列的長度

程式碼

import java.util.Scanner;

public class Z {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int na = scanner.nextInt();
        int nb = scanner.nextInt();
        int[] aa = new int[na];
        int
 
[] bb = new int[nb];
        int i = 0;
        while (scanner.hasNext()) {
            aa[i++] = scanner.nextInt();
            if (i == aa.length) {
                break;
            }
        }
        i = 0;
        while (scanner.hasNext()) {
            bb[i++] = scanner.nextInt();
            if
 
 (i == bb.length) {
                break;
            }
        }

        for (int j = 0; j < aa.length; j++) {
            System.out.print(aa[j] + " ");
        }
        System.out.println();
        for (int j = 0; j < bb.length; j++) {
            System.out.print(bb[j] + " ");
        }
    }
}
 

結果

輸入：
3 4
1 2 3
1 2 3 4
輸出：
1 2 3 
1 2 3 4
