Constructors in java!

What are Constructors ?
They get called automatically when u create an object of a class , that's the simplest definitions we can come out with.
They have to be same name as its class.
like the following example:

public class fun { // creating the fun class

private String courseName; // set variables private

public fun (String name){ // creating a constructor

courseName = name ;

}

public String getCourseName(){ // we need this method to return the private variable

return courseName;

} // close the method

public void displayMessage(){ // displaying method

System.out.printf("this is the name %s", getCourseName());

} // close displaying method

} // close class

 

 

And then displaying and using it in main function as we explained previously.

public class Apples {

public static void main(String[] args){

fun object = new fun("Java class");

 

object.displayMessage();

 

}

}

// Thank you :D
