java中怎样读取控制台输入的整形数据

Answer 1

提供Scanner得做法
import java.util.Scanner;

public class Test {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int input = scanner.nextInt();

}

}

Answer 2

BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
String str = in.readLine();//str就是你控制台输入的一行字符串
int i=Integer.parseInt(str);

Answer 3

public static void main(String[] args) throws IOException {
InputStream is = System.in;
byte[] tmp = new byte[1024];
while (true) {
int i = is.read(tmp, 0, 1024);
System.out.println(new String(tmp, 0, i));
}
}
