default constructor in java code example
Example 1: type of constructor in java
There are three types of constructors:
Default, No-arg constructor and Parameterized.
If you do not implement any constructor in your class,
Java compiler inserts a default constructor into your code on your behalf.
This constructor is known as default constructor.
Constructor with no arguments is known as no-arg constructor
Constructor with arguments(or you can say parameters) is known as
Parameterized constructor.
Example 2: java constructor
class Huso {
public Huso() {
}
}
Example 3: default constructor java
Default constructor is a constructor created by compiler; if user does not
create a constructor in a class.
If user defines a constructor in a class then java compiler will not create
default constructor.
Example 4: default constructor java
class NoteBook{
NoteBook(){
System.out.println("Default constructor");
}
public void mymethod()
{
System.out.println("Void method of the class");
}
public static void main(String args[]){
NoteBook obj = new NoteBook();
obj.mymethod();
}
}
