Let's create a program and use the default and parameterized constructor.In the Employee class, we have created two constructors one is the default constructor and the other is the parameterized constructor. The Employee class has two private variables namely, name and age. In the main method,...
The Sample class contains data members num1, num2, and implemented constructor chaining using the "this" keyword.The Main class contains a static method main(). The main() is an entry point for the program. Here, we created an object obj. We initialized data members of obj using ...

In the above program, we created a public classMainthat contains amain()method. Themain()method is the entry point for the program. In themain()method, we get the list of constructors of theIntegerclass using thegetConstructors()method and printed the constructors using theforeach loop....
The following program gives an example of a default constructor in Java. class Main { int num; boolean flag; public static void main(String[] args) { // A default constructor is called Main obj = new Main(); System.out.println("num:default value = " + obj.num); ...
Below Java program copies the values from one object to another object: ConstructorDemo.java: classConstructorDemo{ intid; String name; //constructor to initialize integer and string ConstructorDemo(inti,String n){ id = i; name = n;
This program will print: The main() method. Hello, World! Types of Java Constructors There are three different types of constructors in Java, we have listed them as follows: Default Constructor No-Args Constructor Parameterized Constructor ...
A)The program has a compile error because you cannot create an object from the class that defines the object. B)The program has a compile error because System.out.println method cannot be invoked from the constructor. C)The program has a compile error because x has not been initialized. D...
