What is the difference between consructor and function in java?

Answer 1

Functions and Constructors are similar in many ways. They can have arguments, they can have any amount of code, they can access the class's variables etc. the only difference is that a method in java needs to mandatorily have a return type but a Constructor in java cannot have a return type. It always creates and returns an object of the class for which it is the constructor. You cannot return a value from a constructor explicitly and if you try to do that, the compiler will give an error. The system knows that the purpose of the constructor is to create an object of the class and it will do the same irrespective of whether you declare a return type or not.

Answer 2

Constructor is a block of code that initializes a newly created object. Function is a group of statements that can be called at any point in the program using its name to perform a specific task. Constructor has the same name as class name.
