How to create a class and it’s instance

// Declaring constructors
public class Blog {

    //public blog(){} //ALERT: doesn't compile as java is case-sensitive
    
    public Blog(){
        System.out.println("default constructor");
    }

    //WARNING: Compiles but it's not a constructor, it's a method
    public void Blog(){};
    /**
     * Constructor can be already a big fun, but 
     * Java offers much more challenges
     * Keep Reading
