Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g.Vectorclass has 4 types of constructors. If you do not want to specify the initial capacity and capacity incremen...

A class contains constructors that are invoked to create objects from the class blueprint. Constructor declarations look like method declarations—except that they use the name of the class and have no return type. For example,Bicyclehas one constructor: Constructor Overloading in Java with exampl...
In Java, it is achieved with the use ofmethod overloading. In method overloading, the method parameters can vary with a number, order, or type of parameter. classPlusOperator{intsum(intx,inty){returnx+y;}doublesum(doublex,doubley){returnx+y;}Stringsum(Strings1,Strings2){returns1.conc...

Method Hiding in Java In Java, we cannot overrideprivate,staticandfinalmethods declared in the parent class into the child classes. Forprivateandfinalmethods, the compiler will give errors. But in case ofstaticmethods, compiler allows to create methods with the same name and arguments....
Method Resolution: The JVM must resolve method calls dynamically, which might introduce slight overhead in method lookup. Deep Inheritance Trees: Excessive inheritance levels can lead to a complex class hierarchy, making debugging and performance tuning difficult. ...
Note: The method that is called is determined during the execution of the program. Hence, method overriding is a run-time polymorphism. 2. Java Method Overloading In a Java class, we can create methods with the same name if they differ in parameters. For example, void func() { ... ...
Document Interfaces: Clearly document the purpose and expected behavior of each method in the interface to guide implementers. Prefer Composition Over Inheritance: Use interfaces to define capabilities and prefer composition over inheritance to achieve flexible and maintainable code. Additional Concepts Multip...
