[PDF] abstract class can be overloaded

An abstract class can contain constructors and static methods. If a class extends the abstract class, it must also implement at least one of the abstract method. An abstract class can contain the main method and the final method. An abstract class can contain overloaded abstract methods.

  • Can an abstract class be overridden?

    A class can override an abstract method by using the same signature as the original method, but with a different body or code. The keyword @Override can be used as an annotation to indicate that a method is overriding another method.

  • Can a class be overloaded?

    If a class has multiple methods having same name but different in parameters, it is known as Method Overloading. If we have to perform only one operation, having same name of the methods increases the readability of the program.

  • Is abstract can be overridden in Java?

    you can override both abstract and normal methods inside an abstract class. only methods declared as final cannot be overridden.
  • We cannot create object of abstract class. It is used to achieve abstraction but it does not provide 100% abstraction because it can have concrete methods. An abstract class must be declared with an abstract keyword. It can have abstract and non-abstract methods.
