Lesson 4 :- Importance of user inputs.

-
In the previous lesson, we got some numbers without using user. In the real world, the inputs are given by users. So we need to know how to get user inputs. This lesson is created to teach it.

Understand about the user inputs using this code.

Special things are we import a class & create an object. You can understand Scanner class and object creation by following the lesson series.

import java.util.Scanner;
class New{
     public static void main(String[} args){
           Scanner s = new Scanner(System.in);
       
      System.out.print("Enter a String: ");
      String a = s.next();
      System.out.println("String is "+a);

      System.out.print("Enter an integer: ");
      int b = s.nextInt();
      System.out.println("Integer is "+b);

     }
}



     





















Try to create a simple calculator using user inputs.

First java program public class First{       public static void main(String[] args){                                                   System.out.println("My First Java Code");             System.out.println("Welcome to the Java World");       } }             This is a very simple java code.First of all I need to tell all of you how to work with java.You know java is a programming language.It helps source file(human readable format) converts to class file(computer readable format). I will explain every things in next lessons.                         There are two common ways to run a java code like this.They are,                    ...

Lesson 6 :- Calling a method

A method is a collection of statements that are grouped together to perform an operation. A method executes when it is called. Try below example & understand what is calling a method. public class New{       public static void main(String[] args){            System.out.println("This is the main method.");            display();            System.out.println("End of the main method.");       }       public static void display(){                  System.out.println("This is the display method.");       } } If we write something under the main method , only those will execute. It means, we need to add all the things what we want to execute, under the main method. It is very basic theory in java programming language.

Lesson 8 :- Creating an object.

Object creation is very important and essential thing in java. We use "new" keyword in this. This is a sample code for object creation. public class Object {     public static void main(String[] args) {               Circle circle = new Circle();         circle.radius = 3.5;         circle.area = 3.14 * circle.radius * circle.radius;         System.out.println("Circle area = "+circle.area);         }     } class Circle{     double radius;     double area; }
