可能是一个愚蠢的问题，我完全不知道如何用我想要的方式来说出来。但是，这是我的问题。我写了一个程序，它完全符合我的要求。这是1700行代码，我没有使用任何面向对象的编程方法。所以我想我自己想在OOP标准中完全改写它。我做了什么。但是，它运行不一样。
所以我想我的问题是。如果我有5个班级和1个班级。这些都是从每个变量继承某些变量，并在main中创建它们的对象。现在当这些变量被程序方法的正常运行改变时。似乎一切都没有改变。那是因为这些类不断发回相同的信息而没有被改变吗？即使我正在更改其特定对象中的值。
我真的不能说出我想要的问题，因为我不是专家，这是我第一次真正尝试完全功能性的OOP计划。所以请尊重我在这里寻求建议，而不是侮辱。
编辑 - 我将提供我的所有代码，以避免更多的混淆。我得到的大部分内容应该足以让我有更好的想法，但是其他一些我无法适应的歌曲类别.nbd

一切都在加载。就像我的旧版本，第一首歌甚至播放，但没有任何更新。图形不会改变，歌曲不会改变。这就是为什么我想知道变量是否在类中没有被改变。我只是想解决这个问题。我道歉。
答案 0 :(得分：1)
如果你有类似的话：
class MyClass {
private int myValue = 0;
public void setMyValue(int newValue) { myValue = newValue; }
}
每次实例化（即创建）类时，都可以设置MyClass的“myValue”变量：
MyClass Zero = new MyClass();
MyClass One = new MyClass();
One.setMyValue(1);
MyClass Two = new MyClass();
Two.setMyValue(2)
对于上面你现在有三个MyClass对象。第一个的myValue为0（默认值）。第二个的值为1，第三个的值为2。
答案 1 :(得分：0)
类的变量和对象的变量在Java中是不同的东西。对象变量是类的所有实例都可以访问的对象，每个实例都有自己的变量值。例如：
class A {
int variable;
}
A的每个实例都可以将自己的值分配给variable。
相比之下，类变量也存在。这些变量不是特定实例的一部分，而是类的一部分。这意味着所有实例共享此变量的相同值。如果更改，则所有实例都将看到此更改。也可以使用类的名称而不是实例的名称来访问该变量。在Java中，类变量是通过将它们声明为static来创建的，例如：
class B {
static int variable;
}
现在B的每个实例都会为variable共享相同的值，并且每个实例都不可能拥有自己的值。
您声明int whatever = 3;的示例将介绍如何创建对象。为类中的变量提供初始值设定项时，所有对象在首次创建变量时都将具有该值。但是，值可以在创建后更改。它相当于将初始化器放在构造函数中。
因此，除非您将变量声明为final，否则在更改它们的值时应该没有问题。
