Question

The following question is about java programming. Is it true or false that one can send in arguments

to a constructor?

Answer 1

Answer:
It is true that one can send arguments to a constructor. Actually, there are two types of constructors:

1. Without arguments: If we do not define a constructor for a class, then the compiler in JAVA creates a default constructor. Now, this default constructor is without any arguments. One thing to note here is that, if we do define a constructor for a class, then there's no creation of default constructor by the JAVA compiler.

2. With arguments: It is very simple to understand. With arguments means that we define a constructor for a class and this constructor is with arguments. We can pass various types of data to a constructor.

I have executed a program where I have sent the argument to a constructor. Here it is if you need it.

Program:

class constructor_with_arguments {

   private String str; // data member of class constructor_with_arguments

   // this is the constructor with arguments, it would receive an argument st
   // of
   // type String
   public constructor_with_arguments(String st) {

       this.str = st; // initializing str with the value of st

   }

   // this is a member function of class constructor_with_arguments
   public String display() {
       return this.str;
   }
}

public class Chegg {

   public static void main(String args[]) {

       // here we are sending the argument to the constructor
       constructor_with_arguments Obj = new constructor_with_arguments("Chegging");

       System.out.println("Hey, Keep " + Obj.display());
   }
}

Note: Please refer to the screenshot of the code to understand the indentation of the code.
