CONSTRUCTOR IN JAVA
Constructor is a special member function of a class which is automatically called whenever a new object is created.
Types of Java constructors:
There are two types of constructors in java are;
1. Default constructor.
2. Parameterized constructor.
1. Default Constructor:
A constructor is called "Default Constructor" when it doesn't have any parameter is know as default constructor.

class_classname()
{
}
Example;
class Table
{
Table()
{
System.out.println("Table is created.");
}
public static void main(String args[])
{
Table b=new Table();
}
}

Table is created.
2. Parameterized Constructor:
A constructor which has a specific number of parameters is called a parameterized constructor.
Example:
public class Person
{
private String name;
private int age;
public Person(String name, int age)
{
this.name = name;
this.age = age;
}
public void printDetails()
{
System.out.println("Name: " + name);
System.out.println("Age: " + age);
}
public static void main(String[] args)
{
Person person = new Person("Jessy", 30);
person.print
Details();
}
}
