Feb 24, 2011 · Constructor can be regarded as static, subclass cannot override its super constructor. Of course, you could call protected-method in super class constructor, then overide it in subclass to change super class constructor.
Jul 30, 2019 · It does not have a return type and its name is same as the class name. But, a constructor cannot be overridden. If you try to write a super class’s constructor in the sub class compiler treats it as a method and expects a return type and generates a compile time error.

1. Overriding and Access Modifiers
The access modifierfor an overriding method can allow more, but not less, access than the overridden method. For example, a protected instance method in the superclass can be made public, but not private, in the subclass. Doing so will generate a compile-time error.
2. Final methods can not be overridden
If we don’t want a method to be overridden, we declare it as final. Please see Using Final with Inheritance. Output
3. Static methods can not be overridden(Method Overriding vs Method Hiding):
When you define a static method with the same signature as a static method in the base class, it is known as method hiding. The following table summarizes what happens when you define a method with the same signature as a method in a super-class.
We can not override the constructor as the parent and child class can never have a constructor with the same name(The constructor name must always be the same as the Class name).
1. Overloadingis about the same method having different signatures. Overriding is about the same method, and same signature but different classes connected through inheritance. 2. Overloading is an example of compiler-time polymorphism and overriding is an example of run-timepolymorphism.

Jan 3, 2014 · No, you cannot override the constructor of the Super class. JVM will definitely call the super class constructor while creating the child class instance. So, whenever you create a subclass instance, it will invoke the baseclass constructor and then continue with the subclass constructor statements. Constructors are not Methods that can be overriden
Feb 1, 2013 · This is fundamentally a bad idea, and you should almost always avoid calling potentially-overridden methods in constructors - or document very clearly that it's going to be the case (so that the subclass code is aware that it can't rely on variables having been initialized appropriately etc).
Aug 14, 2019 · Rule #8: Constructors cannot be overridden. Because constructors are not methods and a subclass’ constructor cannot have same name as a superclass’ one, so there’s nothing relates between constructors and overriding.

Should a subclass call a potentially overridden method in a constructor?
Constructor overloading in Java. In Java, we can overload constructors like methods. The constructor overloading can be defined as the concept of having more than one constructor with different parameters so that every constructor can perform a different task.
