請將由鍵盤中輸入的字元，前後３個 * 包圍，假設輸入的字元是Ａ，則輸出結果為 *** Ａ ***
import java.io.*;
public class hw3_23
{
public static void main(String args[]) throws IOException
{
BufferedReader buf;
String str;
char ch;
buf=new BufferedReader(new InputStreamReader(System.in));
System.out.print(" 請輸入一個字元 :");
str=buf.readLine();
ch=str.charAt(0);
…
}
}
我寫到這...
請問有遺漏什麼嗎?
謝謝
