A constructor is a method.it used to custom intialization
for an object.constructor name and class name is same.
consructor should not return any value not even void also.
A constructor will Executed at the time of initialization of
an object.
Different types of constructors:
--------------------------------
1)default constructor
2)parametarized constructor
Ex:
class sum{
int a,b;//instance variables
sum(int a,int b){
System.out.printl("sum of two numbers="+(a+b));
}
}
class Example{
psvm(String s[])throws Exception{
sum s=new sum(10,10);
}
}
o/p:sum of two numbers=20
/*here the constructor will be executed at the time of
creating the object*/
