如何将Java字符界面转化成GUI

Answer 1

累死了，搂住给我追加分

{
try{
BufferedReader read=new BufferedReader(new InputStreamReader(System.in));
String s=read.readLine();
char c=s.charAt(0);//转换成字符
int a=(int)c;//求出字母的ASCII码
if((a>=97)&&(a<=122))//根据ASCII码判断大小写
System.out.println(s+"大写字母是"+s.toUpperCase());
else if((a>=65)&&(a<=90))
System.out.println("您输入的是大写字母！");
else
System.out.println("您的输入有误！");
}
catch(IOException e)
{
System.out.println("有异常！");}}
