请问在Java中如何通过键盘输入数据?
import java.io.*;
public class CharInput {
public static void main (String args[]) throws java.io.IOException {
String s;
InputStreamReader ir;
BufferedReader in;
ir = new InputStreamReader(System.in);
in = new BufferedReader(ir);
while ((s = in.readLine()) != null) {
System.out.println("Read: " + s);
}
}
}
