Another important point to note while overloading a constructor is: When we don’t implement any constructor, the java compiler inserts the default constructor into our code during compilation, however if we implement any constructor then compiler doesn’t do it. See the example below. publicclas...
Constructor Overloading in Java When we have more than one constructors, then it’s constructor overloading in java. Let’s look at an example of constructor overloading in java program. packagecom.journaldev.constructor;publicclassData{privateStringname;privateintid;//no-args constructorpublicDat...
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 example...

Data Initialization:Each constructor initializes the instance variables x and y according to the provided parameters, demonstrating the concept of constructor overloading in Java. This ensures that the Point class can handle different types of input while maintaining consistent initialization logic. ...
Example 3: Constructor Overloading publicclassCar{String model;int year;// No-Argument ConstructorpublicCar(){model="Unknown";year=0;}// Parameterized ConstructorpublicCar(String model,int year){this.model=model;this.year=year;}publicstaticvoidmain(String[]args){Car car1=newCar();Car car2=ne...
If you don’t mention them, compiler does it for you accordingly.Constructor overloading is possible but overriding is not possible. Which means we can have overloaded constructor in our class but we can’t override a constructor.Constructors can not be inherited.If Super class doesn’t have...
Java Copy In this example, we’ve created a newVehicleobject (myCar) and passed “Blue” as an argument to the constructor. The constructor then sets thecolorproperty to the passed argument, which is “Blue” in this case. Constructor Overloading ...
4.2 Overloading Constructors Another approach to resolve the exception is to modify the existing constructors and provide overloaded versions. Overloading constructors means having multiple constructors with different parameter lists. Let’s modify thePersonclass to include overloaded constructors: ...
Example 2 of Parameterized Constructor in Java: With Overloading There is no limitation on the number of constructors in java we can have multiple constructors in the same class with different parameters. Now let’s discuss this concept with the help of an example. ...
