简单做法 无脑按行打印

解题思路:按行打印

注意事项:别遗漏输入为0的情况

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int n = scanner.nextInt();

int m = scanner.nextInt();

if (n <= 0 || m <= 0) {

return;

}

for (int k = 0; k < n * 2 + 1; k++) {

if (k != 0) {

System.out.println();

}

if (k % 2 == 0) {

pta(m);

} else {

ptb(m);

}

}

}

private static void ptb(int m) {

for (int i = 0; i < m * 2 + 1; i++) {

if (i % 2 == 0) {

System.out.print("|");

} else {

System.out.print(" ");

}

}

}

private static void pta(int m) {

for (int i = 0; i < m * 2 + 1; i++) {

if (i % 2 == 0) {

System.out.print("+");

} else {

System.out.print("-");

}

}

}

}
