Answer 1

What is the difference between methods and constructors?

constructors:

-> It is used to build object of class
-> It binds the instance variable to objects
-> It does not return any thing
-> private constructor can be used to prohibit object creation
-> It get invoked implicitly when we create an object
-> constructor can not have return type

methods:

-> It is part of the class which provides functionality to its objects
-> It may or may not return
-> methods can be reused to another class
-> method have return type or void if no return type
-> methods can be overloaded to inherited class

Example:

class Test{
public Test(){} // default constructor
public Test(int a){} // parameterized constructor

public void print(){} // method with no return

public String toString(){return "hello";} // method with return type
}
