Re: [問題] 用Java寫ACM題目,輸入的問題
※ 引述《StarView (星演)》之銘言：
: 最近在練習用Java寫程式，就找了一題簡單的ACM第476題來解解看.
: languajes. Note that java::io use is restricted; this implies that some
: features (for example, to create a DataInputStream variable with System.in as
: argument, in order to use readLine to read strings from the standard input) are
: not available.
: 所以我的code會compile error是因為用System.in及readLine的原故，
: 我對Java還不是很熟...
: 想請教一下各位高手我該怎麼修改輸入的寫法？ 才能通過ACM java compiler的考驗，
: 另外想請教ACM的Java compiler：gcj也同步支援到jdk5.0嗎？
: 感謝回答..
我沒看你程式...but講一下之前的經驗
只支援到JDK 1.2左右吧...總之很糟糕.....
當初只寫完100~103就沒勇氣再試下去了(汗)
至於輸入的寫法...請善用System.in.read()
網路上的範例碼如下
static String ReadLn (int maxLg) // utility function to read from stdin
{
byte lin[] = new byte [maxLg];
int lg = 0, car = -1;
String line = "";
try
{
while (lg < maxLg)
{
car = System.in.read();
if ((car < 0) || (car == '\n')) break;
lin [lg++] += car;
}
}
catch (IOException e)
{
return (null);
}
if ((car < 0) && (lg == 0)) return (null); // eof
return (new String (lin, 0, lg));
}
