Question

用Java语言从控制台输出空心菱形

我刚学完Java基础，给的答案别太深奥了。

Answer 1

public class Work ...{ public static void main(String[] args) throws IOException ...{ int len; // 菱长 String outstr=new String(); // 输出 int i,j,x,y; BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.println("请输入一个菱长:"); String str = br.readLine(); len=Integer.parseInt(str); for(i=0;i<=len*2;i++)...{ for(j=0;j<=len*2;j++)...{ x=len-i; x=x<0?-1*x:x; y=len+(len-x); outstr+=(j==x||j==y?"*":" "); } outstr+=" "; } System.out.println(outstr); } }

麻烦采纳，谢谢!
