题目
从命令行读入两个数组的长度和数组的值，其中第一行两个数na和nb代表aa和bb数组的长度
代码
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] + " ");
}
}
}
结果
输入： 3 4 1 2 3 1 2 3 4 输出： 1 2 3 1 2 3 4
