还有题目要求最后要输出一个空行没有注意到。

代码：

import java.util.*; public class Main{ public static void n1(int t){ String s=""; for(int i=1;i<=t;i++){ if(i==1||i==t) s=s+"+"; else s=s+"-"; } System.out.println(s); } public static void n2(int t){ String s=""; for(int i=1;i<=t;i++){ if(i==1||i==t) s=s+"|"; else s=s+" "; } System.out.println(s); } public static void main(String[] args) { Scanner cin=new Scanner(System.in); while(cin.hasNext()){ int n=cin.nextInt(); int m=cin.nextInt(); int t=n+2; for(int i=0;i<m+2;i++){ if(i==0||i==m+1) n1(t); else n2(t); } System.out.println(); } } }
