Write a Java program to create Rectangle class with data member length and breadth. Include methods getData() and displayArea() in the class. Finally create an object of Rectangle class and display its area.

 

import java.util.Scanner; 
class Rectangle4{
	int l, b; 
	void getData(){
		Scanner in = new Scanner(System.in); 
		System.out.print("Enter length : "); 
		l=in.nextInt(); 

		System.out.print("Enter breadth : "); 
		b=in.nextInt(); 
	}

	void displayArea(){
		int a; 
		a = l*b; 
		System.out.println("Area = "+a); 
	}

	public static void main(String args[]){
		Rectangle4 obj = new Rectangle4();
		obj.getData(); 
		obj.displayArea();  
	}
}

Define the term class and object? How can you create class and object in Java? Explain with example.

Class is a blueprint to template of real world objects that specifies what data and what methods will be included in object of the class. Class is also called description group of object objects having similar properties. A class is also called user defined data type or programmers defined data type because we can define new data types according to our need by using classes.

Objects are instances of class. We can say that object is variable of class type. Memory for instance declaration rather at the time of class declaration rather than time of object creation. Thus we can say that objects have physical existence and classes are only concepts.

Declaring Classes
Syntax:
[Access Modifier] className{
// body
}

Creating Object
Syntax:
[className] [objectName] = new [className]();

Program

 
class Demo{
 void display(){
  System.out.println("Class Example");
 }
 public static void main(String args[]){
  Demo obj = new Demo(); 
  obj.display(); 
 }
}

What do you mean by JSP? Write a program in the JSP to display Message "I Love Programming" 100 times.

JSP is a Java Server side technology that does all the processing at server. It is used for creating dynamic web application using Java as programming language.

JSP Program to print "I Love Programming" 100 times.
