//How to create an object of a class:

class Base{ // Base is a class name
int num = 5; // Class Variable

public static void main(String[] args){ //Main function

Base obj = new Base(); //Creation of object of Base class

System.out.print(obj.num); //Priting class variable's vlaue
}
}

----- output -----
5

//Adding two numbers; (find error in this program)

About BlueJ
Overview:-
BlueJ is a development environment that allows you to develop Java programs quickly and easily. Its main features are that it is:

Simple BlueJ has a deliberately smaller and simpler interface than professional environments like NetBeans or Eclipse. This allows beginners to get started more quickly, and without being overwhelmed.
Designed for teaching BlueJ is deliberately designed with good pedagogy in mind. There is a popular textbook designed for teaching introductory university/college courses with BlueJ, and a site full of teaching resources.
Interactive BlueJ allows you to interact with objects. You can inspect their value, call methods on them, pass them as parameters and more. You can also directly invoke Java expressions without compiling. Thus BlueJ is a powerful graphical shell/REPL for Java.
Portable BlueJ runs on Windows, Mac OS X, Linux and other platforms which run Java. It can also run without installation from a USB stick.
Mature BlueJ is over fifteen years old, but continues to be updated and supported by a full-time team. We aim to respond to all technical support requests within one working day.
Innovative BlueJ has several features not seen before in other IDEs. Its object bench, code pad, and scope colouring were all original BlueJ features.
