如果我不知道投入的规模已经存在,那么,在阿加瓦邦,究竟是怎样才能保持循环。 在C++中,可以做如下工作。
int main(){
int val;
while(cin >> val){
//do stuff
}
}
在java做类似事情的方法是什么。
Thanks in Advance. Shantanu

你们应当尝试以下事情。
long val;
Scanner sc = new Scanner(System.in).useDelimiter("
");
while (sc.hasNext()) {
String temp = sc.next().trim();
val = Long.parseLong(temp);
// do stuff
}
一种办法是使用斯堪纳语。
long val;
Scanner sc=new Scanner(System.in);
while (sc.hasNextLong() ) {
val = sc.nextLong();
// do stuff
}
这相当于你提供的电压法。 但并不是你要求什么。 只要有法律投入可读体。
根据你的具体要求,采用斯堪的班级的方法。 这句话是一行。 哪一种意味着用户必须进入多数系统。
public static void main(String[] args)
{
String str=new Scanner(System.in).nextLine();
}
不要实施公共汽车。 你可能更喜欢使用溪流。 在数据到来之前,代号(<)被阻断,因此,你的代码将简明扼要,不像你所希望的那样,不忙 lo和工作:
while ( in.read() != -1) {
// do your stuff
}
or even better using buffers:
byte[] buf = new buf[MAX_SIZE]
while ( in.read(buf) != -1) {
// do your stuff
}
i. 相信服务于您目的的最佳途径是,通过多面阅读,一面透镜将等待用户的投入,再让用户知道何时收到。 在时间上,另一个路面将保持循环。
