Yes. Practically Java allows overriding static method, and No theoretically if you Override a static method in Java then it will compile and run smoothly but it will lose Polymorphism which is the basic property of Java. You will Read Everywhere that it is not possible to try yourself compiling and running. you will get your answer. e.g. If you Have Class Animal and a static method eat() and you Override that static method in its Subclass lets called it Dog. Then when wherever you Assign a Dog object to an Animal Reference and call eat() according to Java Dog's eat() should have been called but in static Overriding Animals' eat() will Be Called.

class Animal {
    public static void eat() {
        System.out.println("Animal Eating");
    }
}

class Dog extends Animal{
    public static void eat() {
        System.out.println("Dog Eating");
    }
}

class Test {
    public static void main(String args[]) {
       Animal obj= new Dog();//Dog object in animal
       obj.eat(); //should call dog's eat but it didn't
    }
}


Output Animal Eating

According to Polymorphism Principle of Java, the Output Should be Dog Eating. But the result was different because to support Polymorphism Java uses Late Binding that means methods are called only at the run-time but not in the case of static methods. In static methods compiler calls methods at the compile time rather than the run-time, so we get methods according to the reference and not according to the object a reference a containing that's why You can say Practically it supports static overring but theoretically, it doesn't.

通过重写，我们可以根据对象类型创建一个多态性质。静态方法与对象无关。因此java不支持静态方法重写。

静态方法、变量、块或嵌套类属于整个类而不是对象。

Java中的方法用于公开对象/类的行为。在这里，由于方法是静态的(即静态方法仅用于表示类的行为)，改变/覆盖整个类的行为将违反面向对象编程的基本支柱之一，即高内聚。(记住构造函数在Java中是一种特殊的方法。)

高内聚性——一个类应该只有一个角色。例如:car类应该只生成汽车对象，而不生成自行车、卡车、飞机等。但是Car类可能有一些只属于它自己的特性(行为)。

因此，在设计java编程语言时。语言设计者认为，只有通过使方法本质上是静态的，才能允许开发人员保留类的某些行为。

下面的代码尝试覆盖静态方法，但不会遇到任何编译错误。

public class Vehicle {
static int VIN;

public static int getVehileNumber() {
    return VIN;
}}

class Car extends Vehicle {
static int carNumber;

public static int getVehileNumber() {
    return carNumber;
}}

这是因为，在这里我们没有重写一个方法，而只是重新声明它。Java允许重新声明一个方法(静态/非静态)。

从Car类的getVehileNumber()方法中删除静态关键字将导致编译错误，因为，我们正在尝试改变只属于Vehicle类的静态方法的功能。

此外，如果getVehileNumber()被声明为final，那么代码将无法编译，因为final关键字限制程序员重新声明方法。

public static final int getVehileNumber() {
return VIN;     }

总的来说，这取决于软件设计人员在哪里使用静态方法。 我个人更喜欢使用静态方法来执行某些操作，而不需要创建类的任何实例。第二，对外界隐藏一个类的行为。

重写依赖于类的实例。多态性的意义在于，您可以子类化一个类，而实现这些子类的对象对于父类中定义的相同方法将具有不同的行为(并且在子类中被重写)。静态方法不与类的任何实例相关联，因此这个概念不适用。

There were two considerations driving Java's design that impacted this. One was a concern with performance: there had been a lot of criticism of Smalltalk about it being too slow (garbage collection and polymorphic calls being part of that) and Java's creators were determined to avoid that. Another was the decision that the target audience for Java was C++ developers. Making static methods work the way they do had the benefit of familiarity for C++ programmers and was also very fast, because there's no need to wait until runtime to figure out which method to call.

通过重写，可以实现动态多态。 当您说覆盖静态方法时，您试图使用的词语是矛盾的。

静态表示-编译时，重写用于动态多态性。 两者在性质上是相反的，因此不能同时使用。

动态多态行为发生在程序员使用对象并访问实例方法时。JRE将根据您使用的对象类型映射不同类的不同实例方法。

当你说覆盖静态方法时，我们将使用类名访问静态方法，它将在编译时被链接，因此没有在运行时将方法与静态方法链接的概念。因此，术语“重写”静态方法本身没有任何意义。

注意:即使你用一个对象访问一个类方法，java编译器仍然有足够的智能来发现它，并会做静态链接。

简单的解决方案:使用单例实例。它将允许重写和继承。

在我的系统中，我有SingletonsRegistry类，它为传递的class返回实例。如果没有找到instance，则创建它。

Haxe语言类:

package rflib.common.utils;
import haxe.ds.ObjectMap;



class SingletonsRegistry
{
  public static var instances:Map<Class<Dynamic>, Dynamic>;

  static function __init__()
  {
    StaticsInitializer.addCallback(SingletonsRegistry, function()
    {
      instances = null;
    });

  } 

  public static function getInstance(cls:Class<Dynamic>, ?args:Array<Dynamic>)
  {
    if (instances == null) {
      instances = untyped new ObjectMap<Dynamic, Dynamic>();      
    }

    if (!instances.exists(cls)) 
    {
      if (args == null) args = [];
      instances.set(cls, Type.createInstance(cls, args));
    }

    return instances.get(cls);
  }


  public static function validate(inst:Dynamic, cls:Class<Dynamic>)
  {
    if (instances == null) return;

    var inst2 = instances[cls];
    if (inst2 != null && inst != inst2) throw "Can\'t create multiple instances of " + Type.getClassName(cls) + " - it's singleton!";
  }

}
