Unit - 1 Basic of Core Java Basics of Core JAVA: Class-: A class is a group of objects which have common properties. It is a template or blueprint from which objects are created. It is a logical entity. It can't be physical. A class in Java can contain:  Fields  Methods  Constructors  Blocks  Nested class and interface Syntax to declare a class: class <class_name> { field; method; } Other definition Class-:  A class is the blueprint from which individual objects are created.  A class is a group of objects which have common properties.  It is a template or blueprint from which objects are created.  It is a logical entity. It can't be physical. A class in Java can contain:  Fields.  Methods.  Constructors.  Blocks.  Nested class and interface Class by Example-:  In the real world, you’ll often find many individual objects all of the same kind.  There may be thousands of other bicycles in existence , all of the same make and model.  Each bicycle was built from the same set of blueprints and therefore contains the same components.  In object-oriented terms, we say that your bicycle is an instance of the class of object knows as bicycles. Syntax-: Class className { // variables // methods By Mr. UMESH KUMAR, MCA (GGU)Page | 3

} Here’s an example Program-:write write a program to explain Setter & Getter method with String variable class. class SetterGetterclass { public static void main(String args[]) { A ob = new A(); ob.setMessage("Stylish_Boy"); System.out.println(" Welcome to " + ob.getMessage() + "!!!"); } } class A { private String message; public void setMessage(String msg) { message = msg; } public String getMessage() { return message; } } Output-: Interface-:  An interface is a group of related methods with empty bodies.  The interface in java is a mechanism to achieve fully abstraction.  There can be only abstract method in the java interface not method body. body  It is used to archive fully abstraction and multiple inheritance in java.  Java interface also represents IS IS-A relationship.  It can’t be instantiated just like abstract class.
