public class cd
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
System.out.println("你要输入的内容是"+sc.next());
}
}怎么运行错误。我想输出( 我输入的数)
import java.util.Scanner;//是不是没importpublic class cd { public static void main(String args[]) {Scanner sc = new Scanner(System.in);System.out.println("你要输入的内容是" + sc.next()); }}
