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.java constructor
class MyClass {
public MyClass () {
//constructor code
}
}java constructor
class Huso {
public Huso() {
//constructor code about a huso
}
