How can we avoid class getting overridden?

You can prevent a class from being subclassed by using the final keyword in the class's declaration. Similarly, you can prevent a method from being overridden by subclasses by declaring it as a final method. An abstract class can only be subclassed; it cannot be instantiated.How can we protect sub class to override the method of super class?
To completely replace a superclass's method implementation, simply name your method the same as the superclass method and provide the overriding method with the same signature as the overriden method: class BackgroundThread extends Thread { void run() { . . . } }What methods can not be overridden?
For example, in Java, a method that is declared final in the super class cannot be overridden. Methods that are declared private or static cannot be overridden either because they are implicitly final. It is also impossible for a class that is declared final to become a super class.Which two statements prevent a method from being overridden?
To prevent a method from being overridden, we need to use the "final" keyword.
- Void final act() {} - This statement uses the "final" keyword, so it prevents the method from being overridden.
- Final abstract void act() {} - This statement also uses the "final" keyword, but it also uses the "abstract" keyword.

Solution. Use the MethodInfo. GetBaseDefinition method to determine which method is overridden in what base class. The following overloaded method, FindMethodOverrides , examines all of the static and public instance methods in a class and displays which methods override their respective base class methods.Can we override a class?
Overriding methods in the same classBoth methods should be in two different classes and, these classes must be in an inheritance relation. Both methods must have the same name, same parameters and, same return type else they both will be treated as different methods.
Is it possible to override a class?
