Question

我刚刚开始学习编程。如果尝试编译main.java，则会收到“错误：找不到符号”。

main.java
 public class main {
    public static void main(String[] args) {
        Person dima = new Person();
        System.out.println(dima.height);
    }
}

Person.java
 public class Person {
    int height = 189;
}

E:\study\java> javac Person.java
E:\study\java> javac main.java
main.java:3: error: cannot find symbol
                Person dima = new Person();
                ^
  symbol:   class Person
  location: class main
main.java:3: error: cannot find symbol
                Person dima = new Person();
                                  ^
  symbol:   class Person
  location: class main
2 errors

Answer 1

尝试一下：对我来说很方便

   class Person{
        int height = 100;
    }

    public class main{
         public static void main(String []args){
            Person dima = new Person();
            System.out.println(dima.height);
         }
    }
