method and constructor in java code example

Example 1: constructor in java

A constructor is a special method used to initialize objects in java.
we use constructors to initialize all variables in the class 
when an object is created. As and when an object
is created it is initialized automatically with the help of 
constructor in java.
  
We have two types of constructors:
Default Constructor
Parameterized Constructor

public classname(){
}
public classname(parameters list){
}

Example 2: difference between constructor and method in java

Constructor doesn't have a return
type and it's name must be same as the classname.
Constructor is called automatically when
a new object is created. It’s invoked
implicitly. The Java compiler provides
a default constructor if we don't
 have any constructor.
Constructors are not inherited by child classes.

Method have a return and the
method's name may or not be same as the class name.
Method is invoked explicitly.
Method is not provided by compiler in any case.
Methods are inherited by child classes.
