| Is This Answer Correct ? | 6 Yes | 0 No |
Constructor must have the same as the class name,
whereas we can give any name to the method.
Constructor doesnt have any return type not even void,
whereas method must have valid return type or void if
nothing is return.
Constructor will implicitely invoke at the time of
object creation, whereas method must invoke explicitely
with the object.

Answer / rattaiah addanki
methods:
modifiers_list Return_type Method_name(Parameter_list)
public void withdraw(int accno)
{
business logic
}
1) method is used to provide the business logic of the project
2) the methods are executed whenever wee are calling that
methods.
3) every method having return type.
Constructors:-
Modifiers_list Constructor_name(parameters)
ex:- public Test(int i)
1) where as constructors are used to create object.
2) the constructor is executed then only object is created.
3) at the time of object creation the constructors are
executed no need of calling.
4) if we want to execute any code at time of the object
creation then we should go for constructors concept.
