The Java programming language supports overloading methods, and Java can distinguish between methods with different method signatures. This means that methods within a class can have the same name if they have different parameter lists (there are some qualifications to this that will be discussed in...
Here we have multipledrawmethods but they have different behavior. This is a case of method overloading because all the methods name is same and arguments are different. Here compiler will be able to identify the method to invoke at compile-time, hence it’s called compile-time polymorphism....

4. Constructor Chaining withthis()andsuper() In Java, it is possible to call other constructors inside a constructor. It is just like method calling but without any reference variable (obviously, as the instance is NOT fully initialized as of now). ...

Overloading与Overriding浅解 1.重载(Overloading) (1)方法重载是让类以统一的方式处理不同类型数据的一种手段。多个同名函数同时 存在,具有不同的参数个数/类型。重载Overloading是一个类中多态性的一种表现。 (2)Java的方法重载,就是在类中可以创建多个方法,它们具有相同的名字,但具...
重写Overriding是父类与子类之间多态性的一种表现,重载Overloading是一个类中多态性的一种表现。如果在子类中定义某方法与其父类有相同的名称和参数,我们说该方法被重写 (Overriding)。子类的对象使用这个方法时,将调用子类中的定义,对它而言,父类中的定义如同被"屏蔽"了。如果在一个类中定义了多个同名的方法,...
Method Overloading forms compile-time polymorphism. Example of Method Overloading: class A1 { void hello() { Console.WriteLine("Hello"); } void hello(string s) { Console.WriteLine("Hello {0}",s); } } Example of Run Time Polymorphism Method Overriding: Method overriding occurs when child...
