Java公共访问修饰符 [英] Java public access modifier

问题描述

我创建了一个类如下。

I have created a class as follows.

package basics;


 public class Basics {

   public int intMaths;
   public int intEnglish;
   public int intScience;

   }

然后我创建了另一个类，如下所示，这两个类都在相同的包。

Then I have created another class as the following and both classes are in the same package.

package basics;

 public class AccessVaria {



 }

现在我想从AccessVaria访问Basics.java类中的变量.java类。



我试过这样做这个

Now I want to access the variable in the Basics.java class from the AccessVaria.java class.

I have tried to do that like this

intMaths = 80;

但我不能这样做并给我一个建议。 java总是请求getter（）&即使变量具有公共访问修饰符，setter（）方法也可以从不同的类访问变量？



我可以从C＃中的另一个类访问一个类中的公共变量。净，但他们没有给出如此糟糕的经历。



所以，如果有人能解释如何解决这个问题？



谢谢！

But I cannot do that and give me a suggestion. Do java always request for getter() & setter() methods to access variables from different classes even if the variables have the public access modifier ?

I have access public variables in one class from another class in C#.Net but they didn't give suchlike bad experience.

So if someone can explain how to solve this matter ?

Thank You!

推荐答案

在Java中，要访问给定类的任何属性，您必须创建首先是对象。

因此，如果要在类 AccessVaria Basics 的属性>，然后你必须在 AccessVaria 里面创建一个类 Basics 的实例。

.. java总是请求getter（）& setter（）方法来访问varia bles ..



Java建议您不要直接访问属性，使用getter / setter方法访问属性。这是一种编码惯例。

In Java, to access any properties of a given class, you have to create the object first.
Therefore if you want to access the properties of class Basics inside class AccessVaria , then you have to create a instance of class Basics inside AccessVaria.

Java suggest you not to access the properties directly, use getter/setter method to access the properties. It is a coding convention.
