标题[问题] 如何简化此程式?
时间Thu Jun 1 22:16:22 2006
public class Et01
{
public static void main (String[] args) throws java.io.IOException
{
java.io.BufferedReader keyin;
keyin = new java.io.BufferedReader(new java.io.InputStreamReader(System.in));
System.out.print("请输入五个英文字元(大小写不拘)：");
String K = keyin.readLine();
char[] X = K.toCharArray();
int L = (int)K.length();
f1:{
if (L == 5)
{
for (int i = 0; i <= 4; i++)
{
int c = (int)K.charAt(i);
if (64 >= c || (93 <= c && c <= 96) || 125 <= c)
{
System.out.print("仅能接受英文字元");
break f1;
}
}
for (int i = 0; i <= 4; i++)
{
int c = (int)K.charAt(i);
if (65 <= c && c <= 92)
X[i] = (char)(c+32);
else if (97 <= c && c <= 124 )
X[i] = (char)(c-32);
System.out.print(X[i]);
}
}
else
System.out.println("输入长度错误");
}
}
}
上述程式是用来将英文字元大小写互换。
请问各位大大，小弟该如何简化code呢@@？
