Java中用命令行界面,JCreator怎么输入数据??

import java.util.*;

public class Console {

static Scanner san = new Scanner(System.in);

public static void main(String[] args) {
int n = 1;
while(n <= 5) {
System.out.print("请输入第" + n + "个值: ");
String strn = san.next();//请查阅Scanner 相关API
System.out.println("你输入的是: " + strn);
n ++;
}
}

}

scanner函数
