We cannot create object for an abstract class. Program to calculate area and circumference of Circle In this program, radius value is specified in the program and we are calculating the area and circumference using the above mentioned formulas. Requirement Read one side of a rectangle from console Then read another side of rectangle Calculate the area of the rectangle Assign the area to a value. We are using area class for declaring object of findArea class. Program 1: User would provide the length and width values during execution of the program.
#JAVA PROGRAM TO FIND AREA OF RECTANGLE USING SCANNER HOW TO#
We have defined an abstract class called calcArea and defined four abstract methods in it each having one or more parameters.įindArea class inherits calcArea class and the body of methods are defined here. In this tutorial we will see how to calculate Area of Rectangle. Write a C Program to find Area of a Rectangle using length and width with example. Enter breadth of rectangle : ') double breadth scanner. Coming to the program in this tutorial we are calculating Area of Triangle, Rectangle, Square and Circle. This is a Java the perimeter is 2 width + 2 length. double length scanner.nextDouble () ('2. So we need to inherit the abstract class and define the abstract methods in the new class. If we place abstract keyword before a method, we cannot define body of the method. Placing a abstract keyword before the class name defines the class as abstract. Using Return and Switch in Java with the area of shapes. It means that you should put a scanner inside setDim().In this tutorial we will be learning how to define a abstract class and methods. Java program to find area of circle and rectangle using interface We can use interface to find area of circle and rectangle.
Length and breadth of rectangle are entered through keyboard. Shares Let’s learn java program to find area of circle and rectangle using interface. Secondly: First method named as 'setDim' takes length and breadth of rectangle as parameters. It means that you should put a scanner inside setDim(). Length and breadth of rectangle are entered through keyboard. It means that "return result" should be on getArea() and not on setDim(). Firstly: Method named as 'getArea' returns the area of the rectangle.here you have to use getter and setter,in setter we have to set the values and return it so no void,and in case //of getter we have to get the values ehich means we have to return something. Please can someone answer this question - The following program calculates area of a rectangle in Java.Length and breadth of rectangle are entered through keyboard This class will take the height and width of the rectangle in its constructor. First method named as 'setDim' takes length and breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. Steps for the program: We will follow the following steps: Create one Rectangle class. Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. First method named as 'setDim' takes length and
