这种错误该怎么办？
这是慕课网的问题，不用太计较，试试下面这个：
public class HelloWorld{
public static void main(String[] args) {
String name="爱慕课";
char sex='男';
int num=18;
double price=120.5;
boolean isOK=true;
System.out.println(name);
System.out.println(sex);
System.out.println(num);
System.out.println(price);
System.out.println(isOK);
}
}求采纳！
