One of the most common issues with inheritance is the dispute over assets. When an estate's value is high, and multiple beneficiaries are involved, this can cause problems.
Inheritance provides several advantages including reusability, saving time and effort, data hiding, extensibility, easy understandability, and reliability. An abstract class serves as a base class that cannot be instantiated on its own but provides common functionality to derived classes.
Inheritance is not bad per se and is a very powerful (essential) tool to use in creating OO structures. However when not used properly (that is when used for something else than creating Object structures) it creates code that is very tightly coupled and very hard to maintain.
d. One big superclass can be used instead of many little classes. - This is NOT an advantage of inheritance.
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent ...
Disadvantages of Inheritance
Inherited functions work slower than normal function as there is indirection. Improper use of inheritance may lead to wrong solutions. Often, data members in the base class are left unused which may lead to memory wastage.
Sometimes, inheritance is used inappropriately, for example, when classes are derived not because they represent an "is-a" relationship (which is ideal for inheritance), but because they share some common functionalities. In such cases, composition or interface implementation might be a better approach.
People who commit inheritance theft, whether it's an executor, trustee, beneficiary or someone else, may be subject to both criminal and civil penalties. For example, a trustee who embezzles money from someone's estate can be charged with a felony or misdemeanor, depending on state laws.
Several basic modes of inheritance exist for single-gene disorders: autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive.
In this example, Animal is the superclass, Dog is the subclass of Animal, and Labrador is the subclass of Dog. The Labrador class inherits the eat() method from the Animal class and the bark() method from the Dog class.
Miscommunications about your final wishes. Old-fashioned sibling rivalry. Emotional attachment to certain assets, such as the family cabin. Varying financial needs between beneficiaries.
Small inheritance ($20,000)
Even if you receive a modest inheritance—you have many options. One idea is to fund an emergency savings account.
If you are the designated beneficiary on a deceased person's bank account, you typically can go to the bank immediately following their death to claim the asset. In general, there is no waiting period for beneficiaries to access the money; however, keep in mind that laws can vary by state and by bank.
Inheritance can lead to tight coupling between classes, making it difficult to change one class without affecting others. When a child class inherits from a parent class, it is tightly coupled to the parent class, making it difficult to modify the parent class without breaking the child class.
Step-children who weren't adopted by the person who died can't inherit under the rules of intestacy. If a child is under 18, they can't receive their inheritance until they're 18 years old. The inheritance will be held in a trust. Until then, an adult called a 'trustee' will manage the inheritance on their behalf.
Giving away assets during your lifetime can be helpful for others and rewarding for you personally and financially. You can enjoy the satisfaction of watching others put your assets to good use, and you can provide funds sooner rather than later, possibly when the money is needed most.

The conventional wisdom is that inheritances contribute to the overall inequality of household wealth. Moreover, it is commonly believed that inheritances impede intergenerational wealth mobility and play an important role in accounting for the intergenerational transmission of economic and social privilege.
Java disallows multiple inheritance to avoid the complexity and ambiguity associated with it, particularly the "diamond problem," where a class inherits from two classes that have a common ancestor, leading to conflicts in the inheritance of methods.
