不会改代码

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);

}

}
